The AD8417 is a single-supply, zero drift, difference amplifier that uses a unique architecture to accurately amplify small differential current shunt voltages in the presence of rapidly changing common-mode voltages. The reference inputs, VREF1 and VREF2, are tied through 100 k resistors to the positive input of the main amplifier, which allows the output offset to be adjusted anywhere in the output operating range. The gain is 1 V/V from the reference pins to the output when the reference pins are used in parallel. When the pins are used to divide the supply, the gain is 0.5 V/V. In typical applications, the AD8417 measures current by amplifying the voltage across a shunt resistor connected to its inputs by a gain of 60 V/V (see Figure 26). The AD8417 design provides excellent common-mode rejection, even with PWM common-mode inputs that can change at very fast rates, for example, 1 V/ns. The AD8417 contains patented technology to eliminate the negative effects of such fast changing external common-mode variations. The AD8417 offers breakthrough performance without compromising any of the robust application needs typical of solenoid or motor control. The ability to reject PWM input common-mode voltages and the zero drift architecture providing low offset and offset drift allows the AD8417 to deliver total accuracy for these demanding applications. The AD8417 features an input offset drift of less than 0.4 V/C. This performance is achieved through a novel zero drift VCM = -2V TO +70V VS = 2.7V TO 5.5V 70V VS VREF 1 AD8417 VCM +IN ISHUNT EMI FILTER OUT G = 60 RSHUNT 50A VOUT + 0V -IN VS VS/2 EMI FILTER - ISHUNT VREF 2 -50A Figure 26. Typical Application Rev. C | Page 10 of 16 11882-225 0V GND Data Sheet AD8417 The output of the AD8417 can be adjusted for unidirectional or bidirectional operation. UNIDIRECTIONAL OPERATION Unidirectional operation allows the AD8417 to measure currents through a resistive shunt in one direction. The basic modes for unidirectional operation are ground referenced output mode and VS referenced output mode. VS Referenced Output Mode VS referenced output mode is set when both reference pins are tied to the positive supply. It is typically used when the diagnostic scheme requires detection of the amplifier and the wiring before power is applied to the load (see Figure 28). VS For unidirectional operation, the output can be set at the negative rail (near ground) or at the positive rail (near VS) when the differential input is 0 V. The output moves to the opposite rail when a correct polarity differential input voltage is applied. The required polarity of the differential input depends on the output voltage setting. If the output is set at the positive rail, the input polarity must be negative to decrease the output. If the output is set at ground, the polarity must be positive to increase the output. AD8417 R4 -IN VS + R2 VREF 1 R3 VREF 2 Figure 28. VS Referenced Output BIDIRECTIONAL OPERATION Bidirectional operation allows the AD8417 to measure currents through a resistive shunt in two directions. In this case, the output is set anywhere within the output range. Typically, it is set at half-scale for equal range in both directions. In some cases, however, it is set at a voltage other than half scale when the bidirectional current is nonsymmetrical. AD8417 R4 - Adjusting the output is accomplished by applying voltage(s) to the referenced inputs. VREF1 and VREF2 are tied to internal resistors that connect to an internal offset node. There is no operational difference between the pins. OUT + +IN OUT GND When using the AD8417 in ground referenced output mode, both referenced inputs are tied to ground, which causes the output to sit at the negative rail when there are zero differential volts at the input (see Figure 27).

C | Page 11 of 16 AD8417 Data Sheet EXTERNAL REFERENCED OUTPUT VS Tying both pins together and to a reference produces an output equal to the reference voltage when there is no differential input (see Figure 29). The output decreases the reference voltage when the input is negative, relative to the -IN pin, and increases when the input is positive, relative to the -IN pin.

Split an external reference by connecting one VREFx pin to ground and the other VREFx pin to the reference (see Figure 31). Figure 29.

Split External Reference 5V 11882-029 By tying one reference pin to VS and the other to the ground pin, the output is set at half of the supply when there is no differential input (see Figure 30). The benefit of this configuration is that an external reference is not required to offset the output for bidirectional current measurement. Tying one reference pin to VS and the other to the ground pin creates a midscale offset that is ratiometric to the supply, which means that if the supply increases or decreases, the output remains at half the supply. For example, if the supply is 5.0 V, the output is at half scale or 2.5 V. If the supply increases by 10% (to 5.5 V), the output increases to 2.75 V. Data Sheet AD8417 APPLICATIONS INFORMATION 3-Phase Motor Control The AD8417 is ideally suited for monitoring current in 3-phase motor applications. The 250 kHz typical bandwidth of the AD8417 provides instantaneous current monitoring. Additionally, the typical low offset drift of 0.1 V/C means that the measurement error between the two motor phases is at a minimum over temperature. The AD8417 rejects PWM input common-mode voltages in the -2 V to +70 V (with a 5 V supply) range. Monitoring the current on the motor phase allows sampling of the current at any point and provides diagnostic information, such as a short to GND and battery. Refer to Figure 33 for the typical phase current measurement setup with the AD8417. this type of application. The instability of the ground reference causes inaccuracies in the measurements that can be made with a simple ground referenced op amp. The AD8417 measures current in both directions as the H-bridge switches and the motor changes direction. The output of the AD8417 is configured in an external referenced bidirectional mode (see the Bidirectional Operation section). CONTROLLER 5V MOTOR VS +IN VREF 1 -IN GND VREF 2 OUT AD8417 SHUNT NC 2.5V H-Bridge Motor Control Another typical application for the AD8417 is to form part of the control loop in H-bridge motor control. In this case, place the shunt resistor in the middle of the H-bridge to accurately measure current in both directions by using the shunt available at the motor (see Figure 32). Using an amplifier and shunt in this location is a better solution than a ground referenced op amp because ground is not typically a stable reference voltage in Figure 32.

High voltage is present at the inputs of the current sense amplifier. When the shunt is battery referenced, the AD8417 produces a linear ground referenced analog output. Additionally, the AD8214 provides an overcurrent detection signal in as little as 100 ns (see Figure 36). This feature is useful in high current systems where fast shutdown in overcurrent conditions is essential. OUTPUT 5 4 11882-032 8 NC = NO CONNECT. 3 High Rail Current Sensing -IN 3 2 Figure 35.

Tie an inductive load (solenoid) to a power supply and place a resistive shunt between the switch and the load (see Figure 34). An advantage of placing the shunt on the high side is that the entire current, including the recirculation current, is measurable because the shunt remains in the loop when the switch is off. In addition, diagnostics are enhanced because shorts to ground are detected with the shunt on the high side.

In this case, when the switch is open, the voltage reversal across the inductive load causes the common-mode voltage to be held one diode drop below ground by the clamp diode. VS 1 The high-side current sense with a high-side switch configuration minimizes the possibility of unexpected solenoid activation and excessive corrosion (see Figure 35). In this case, both the switch and the shunt are on the high side. When the switch is off, the battery is removed from the load, which prevents damage from potential shorts to ground while still allowing the recirculating current to be measured and to provide diagnostics. Removing the power supply from the load for the majority of the time that the switch is open minimizes the corrosive effects that can be caused by the differential voltage between the load and ground. +IN High-Side Current Sense with a High-Side Switch Figure 36.
