Si823x Data Sheet 0.5 and 4.0 Amp ISOdrivers (2.5 and 5 kVRMS) The Si823x isolated driver family combines two independent, isolated drivers into a single package. The Si8230/1/3/4 are high-side/low-side drivers, and the Si8232/5/6/7/8 are dual drivers. Versions with peak output currents of 0.5 A (Si8230/1/2/7) and 4.0 A (Si8233/4/5/6/8) are available. All drivers operate with a maximum supply voltage of 24 V. The Si823x drivers utilize Silicon Labs' proprietary silicon isolation technology, which provides up to 5 kVRMS withstand voltage per UL1577 and fast 60 ns propagation times. Driver outputs can be grounded to the same or separate grounds or connected to a positive or negative voltage. The TTL level compatible inputs with >400 mV hysteresis are available in individual control input (Si8230/2/3/5/6/7/8) or PWM input (Si8231/4) configurations. High integration, low propagation delay, small installed size, flexibility, and cost-effectiveness make the Si823x family ideal for a wide range of isolated MOSFET/IGBT gate drive applications.

This simple architecture provides a robust isolated data path and requires no special considerations or initialization at start-up. A simplified block diagram for a single Si823x channel is shown in the figure below. Transmitter Receiver Driver RF OSCILLATOR VDD A Dead time control MODULATOR SemiconductorBased Isolation Barrier B DEMODULATOR 0.5 to 4 A peak Gnd Figure 3.4. Simplified Channel Diagram A channel consists of an RF Transmitter and RF Receiver separated by a semiconductor-based isolation barrier. Referring to the Transmitter, input A modulates the carrier provided by an RF oscillator using on/off keying. The Receiver contains a demodulator that decodes the input state according to its RF energy content and applies the result to output B via the output driver. This RF on/off keying scheme is superior to pulse code schemes as it provides best-in-class noise immunity, low power consumption, and better immunity to magnetic fields.

Rev. 1.8 | 13 Si823x Data Sheet System Overview 3.6 Power Supply Connections Isolation requirements mandate individual supplies for VDDI, VDDA, and VDDB. The decoupling caps for these supplies must be placed as close to the VDD and GND pins of the Si823x as possible. The optimum values for these capacitors depend on load current and the distance between the chip and the regulator that powers it. Low effective series resistance (ESR) capacitors, such as Tantalum, are recommended. silabs.com | Smart. Connected. Energy-friendly. Rev. 1.8 | 14 Si823x Data Sheet System Overview 3.7 Power Dissipation Considerations Proper system design must assure that the Si823x operates within safe thermal limits across the entire load range.The Si823x total power dissipation is the sum of the power dissipated by bias supply current, internal parasitic switching losses, and power dissipated by the series gate resistor and load. Equation 1 shows total Si823x power dissipation. ( )( )( ) ( )( )( ) Rp Rp PD = (VDDI)(IDDI) + 2(IDD2)(VDD2) + f QTL VDD2 + f QTL VDD2 + 2fCintVDD22 Rp + Rg Rp + Rg where: PD is the total Si823x device power dissipation (W) IDDI is the input-side maximum bias current (3 mA) IDD2 is the driver die maximum bias current (2.5 mA) Cint is the internal parasitic capacitance (75 pF for the 0.5 A driver and 370 pF for the 4.0 A driver) VDDI is the input-side VDD supply voltage (2.7 to 5.5 V) VDD2 is the driver-side supply voltage (10 to 24 V) f is the switching frequency (Hz) QTL is the gate charge of the FET being driven RG is the external gate resistor RP is the RDS(ON) of the driver pull-up switch: (Rp = 15 for the 0.5 A driver; Rp = 2.7 for the 4.0 A driver) Rn is the RDS(ON) of the driver pull-down switch: (Rn = 5 for the 0.5 A driver and 1 for the 4.0 A driver) Equation 1. Power dissipation example for 0.5 A driver using Equation 1 with the following givens: VDDI = 5.0 V VDD2 = 12 V f = 350 kHz RG = 22 QG = 25 nC ( ) ( ) 5 +522 Pd = 0.015 + 0.060 + 350 x 103 (25 x 10-9) 12 + 2 (350 x 103)(75 x 10-12)(144) = 145 mW From which the driver junction temperature is calculated using Equation 2, where: Pd is the total Si823x device power dissipation (W) ja is the thermal resistance from junction to air (105 C/W in this example) TA is the ambient temperature T j = Pd x ja x T A = (0.145)(105) + 20 = 35.2o C The maximum power dissipation allowable for the Si823x is a function of the package thermal resistance, ambient temperature, and maximum allowable junction temperature, as shown in Equation 2: PDmax Tjmax - TA ja where: PDmax = Maximum Si823x power dissipation (W) silabs.com | Smart. Connected. Energy-friendly. Rev. 1.8 | 15 Si823x Data Sheet System Overview Tjmax = Si823x maximum junction temperature (150 C) TA = Ambient temperature (C) ja = Si823x junction-to-air thermal resistance (105 C/W) f = Si823x switching frequency (Hz) Equation 2. Substituting values for PDmax Tjmax, TA, and ja into Equation 2 results in a maximum allowable total power dissipation of 1.19 W. Maximum allowable load is found by substituting this limit and the appropriate data sheet values from Table 4.1 Electrical Characteristics1 on page 21 into Equation 1 and simplifying. The result is Equation 3 (0.5 A driver) and Equation 4 (4.0 A driver), both of which assume VDDI = 5 V and VDDA = VDDB = 18 V. CL(MAX) = 1.4 x 10-3 - 7.5 x 10-11 f Equation 3. CL(MAX) = 1.4 x 10-3 - 3.7 x 10-10 f Equation 4. Equation 3 and Equation 4 are graphed in the figure below, where the points along the load line represent the package dissipationlimited value of CL for the corresponding switching frequency. 3.8 Layout Considerations It is most important to minimize ringing in the drive path and noise on the Si823x VDD lines. Care must be taken to minimize parasitic inductance in these paths by locating the Si823x as close to the device it is driving as possible. In addition, the VDD supply and ground trace paths must be kept short. For this reason, the use of power and ground planes is highly recommended. A split ground plane system having separate ground and VDD planes for power devices and small signal components provides the best overall noise performance. silabs.com | Smart. Connected.

Rev. 1.8 | 16 Si823x Data Sheet System Overview 3.9 Undervoltage Lockout Operation Device behavior during start-up, normal operation and shutdown is shown in Figure 3.30 Device Behavior during Normal Operation and Shutdown on page 17, where UVLO+ and UVLO- are the positive-going and negative-going thresholds respectively. Note that outputs VOA and VOB default low when input side power supply (VDDI) is not present. 3.9.1 Device Startup Outputs VOA and VOB are held low during power-up until VDD is above the UVLO threshold for time period tSTART. Following this, the outputs follow the states of inputs VIA and VIB. 3.9.2 Undervoltage Lockout Undervoltage Lockout (UVLO) is provided to prevent erroneous operation during device startup and shutdown or when VDD is below its specified operating circuits range. The input (control) side, Driver A and Driver B, each have their own undervoltage lockout monitors. The Si823x input side enters UVLO when VDDI < VDDIUV-, and exits UVLO when VDDI > VDDIUV+. The driver outputs, VOA and VOB, remain low when the input side of the Si823x is in UVLO and their respective VDD supply (VDDA, VDDB) is within tolerance. Each driver output can enter or exit UVLO independently. For example, VOA unconditionally enters UVLO when VDDA falls below VDDAUV- and exits UVLO when VDDA rises above VDDAUV+.

Connected. Energy-friendly. Rev. 1.8 | 17 Si823x Data Sheet System Overview 3.9.3 Undervoltage Lockout (UVLO) The UVLO circuit unconditionally drives VO low when VDD is below the lockout threshold. Referring to Figure 3.31 Si823x UVLO Response (5 V) on page 18 through Figure 3.34 Si823x UVLO Response (12.5 V) on page 18, upon power up, the Si823x is maintained in UVLO until VDD rises above VDDUV+. During power down, the Si823x enters UVLO when VDD falls below the UVLO threshold plus hysteresis (i.e., VDD < VDDUV+ - VDDHYS). Figure 3.31. Si823x UVLO Response (5 V) Figure 3.32. Si823x UVLO Response (10 V) Figure 3.33. Si823x UVLO Response (8 V) Figure 3.34. Si823x UVLO Response (12.5 V) 3.9.4 Control Inputs VIA, VIB, and PWM inputs are high-true, TTL level-compatible logic inputs. A logic high signal on VIA or VIB causes the corresponding output to go high. For PWM input versions (Si8231/4), VOA is high and VOB is low when the PWM input is high, and VOA is low and VOB is high when the PWM input is low. 3.9.5 Disable Input When brought high, the DISABLE input unconditionally drives VOA and VOB low regardless of the states of VIA and VIB. Device operation terminates within tSD after DISABLE =VIH and resumes within tRESTART after DISABLE = VIL. The DISABLE input has no effect if VDDI is below its UVLO level (i.e., VOA, VOB remain low). silabs.com | Smart. Connected. Energy-friendly. Rev. 1.8 | 18 Si823x Data Sheet System Overview 3.10 Programmable Dead Time and Overlap Protection All high-side/low-side drivers (Si8230/1/3/4) include programmable overlap protection to prevent outputs VOA and VOB from being high at the same time. These devices also include programmable dead time, which adds a user-programmable delay between transitions of VOA and VOB. When enabled, dead time is present on all transitions, even after overlap recovery. The amount of dead time delay (DT) is programmed by a single resistor (RDT) connected from the DT input to ground per Equation 5. Note that the dead time pin can be tied to VDDI or left floating to provide a nominal dead time at approximately 400 ps. DT 10 x RDT where: DT = dead time (ns) and RDT = dead time programing resistor (k) Equation 5. The device driving VIA and VIB should provide a minimum dead time of TDD to avoid activating overlap protection. Input/output timing waveforms for the two-input drivers are shown in Figure 3.35 Input / Output Waveforms for High-Side / Low-Side Two-Input Drivers on page 19, and dead time waveforms are shown in Figure 3.36 Dead Time Waveforms for High-Side / Low-Side Two-input Drivers on page 20.

Applications The following examples illustrate typical circuit configurations using the Si823x. 5.1 High-Side/Low-Side Driver The Figure A in the drawing below shows the Si8230/3 controlled using the VIA and VIB input signals, and Figure B shows the Si8231/4 controlled by a single PWM signal.

Si823x in Half-Bridge Application For both cases, D1 and CB form a conventional bootstrap circuit that allows VOA to operate as a high-side driver for Q1, which has a maximum drain voltage of 1500 V. The boot-strap start up time will depend on the CB cap chosen. See application note, "AN486: HighSide Bootstrap Design Using Si823x ISODrivers in Power Delivery Systems". VOB is connected as a conventional low-side driver, and, in most cases, VDD2 is the same as VDDB. Note that the input side of the Si823x requires VDD in the range of 4.5 to 5.5 V (2.7 to 5.5 V for Si8237/8), while the VDDA and VDDB output side supplies must be between 6.5 and 24 V with respect to their respective grounds. It is recommended that bypass capacitors of 0.1 and 1 F value be used on the Si823x input side and that they be located as close to the chip as possible. Moreover, it is recommended that 0.1 and 10 F bypass capacitors, located as close to the chip as possible, be used on the Si823x output side to reduce high-frequency noise and maximize performance. silabs.com | Smart. Connected. Energy-friendly. Rev. 1.8 | 31 Si823x Data Sheet Applications 5.2 Dual Driver The figure below shows the Si823x configured as a dual driver. Note that the drain voltages of Q1 and Q2 can be referenced to a common ground or to different grounds with as much as 1500 V dc between them.

Si8232/5/7/8 in a Dual Driver Application Because each output driver resides on its own die, the relative voltage polarities of VOA and VOB can reverse without damaging the driver. That is, the voltage at VOA can be higher or lower than that of VOB by VDD without damaging the driver. Therefore, a dual driver in a low-side high side/low side drive application can use either VOA or VOB as the high side driver. Similarly, a dual driver can operate as a dual low-side or dual high-side driver and is unaffected by static or dynamic voltage polarity changes. 5.3 Dual Driver with Thermally Enhanced Package (Si8236) The thermal pad of the Si8236 must be connected to a heat spreader to lower thermal resistance. Generally, the larger the thermal shield's area, the lower the thermal resistance. It is recommended that thermal vias also be used to add mass to the shield. Vias generally have much more mass than the shield alone and consume less space, thus reducing thermal resistance more effectively. While the heat spreader is not generally a circuit ground, it is a good reference plane for the Si8236 and is also useful as a shield layer for EMI reduction. With a 10mm2 thermal plane on the outer layers (including 20 thermal vias), the thermal impedance of the Si8236 was measured at 50 C/W. This is a significant improvement over the Si8235 which does not include a thermal pad. The Si8235's thermal resistance was measured at 105 C /W. In addition, note that the GNDA and GNDB pins for the Si8236 are connected together through the thermal pad. silabs.com | Smart. Connected. Energy-friendly.
