Freescale Semiconductor Advance Information Document Number: MPC17533 Rev. 3.0, 7/2006 0.7 A 6.8 V Dual H-Bridge Motor Driver 17533 The 17533 is a monolithic dual H-Bridge power IC ideal for portable electronic applications containing bipolar stepper motors and/or brush DC-motors (e.g., cameras and disk drive head positioners). The 17533 operates from 2.0 V to 6.8 V, with independent control of each H-Bridge via parallel MCU interface (3.0 V- and 5.0 V-compatible logic). The device features built-in shoot-through current protection and an undervoltage shutdown function. The 17533 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). The 17533 has a low total RDS(ON) of 1.2 (max @ 25C). The 17533's low output resistance and high slew rates provide efficient drive for many types of micromotors.

The device features built-in shootthrough current protection and undervoltage shutdown. The 17533 has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). The MOSFETs comprising the output bridge have a total source + sink RDS(ON) 1.2 . The 17533 can simultaneously drive two brush DC motors or, as shown in the simplified application diagram on page 1, one bipolar stepper motor. The drivers are designed to be PWM'ed at frequencies up to 200 kHz. FUNCTIONAL PIN DESCRIPTION LOGIC SUPPLY (VDD) The VDD pin carries the logic supply voltage and current into the logic sections of the IC. VDD has an undervoltage threshold. If the supply voltage drops below the undervoltage threshold, the output power stage switches to a tri-state condition. When the supply voltage returns to a level that is above the threshold, the power stage automatically resumes normal operation according to the established condition of the input control pins. LOGIC INPUT CONTROL (IN1A, IN1B, IN2A, AND IN2B) These logic input pins control each H-Bridge output (e.g., IN1A logic HIGH = OUT1A HIGH, etc.). However, if all inputs are taken HIGH, the outputs bridges are both tri-stated (refer to Table 5, Truth Table, page 7). OUTPUT ENABLE (OE) The OE pin is a LOW = TRUE enable input. When OE = HIGH, all H-Bridge outputs (OUT1A, OUT1B, OUT2A, and OUT2B) are tri-stated (high-impedance), regardless of logic inputs (IN1A, IN1B, IN2A, and IN2B) states. OUTPUT A AND B OF H-BRIDGE CHANNEL 1 AND 2 (OUT1A, OUT1B, OUT2A, AND OUT2B) These pins provide connection to the outputs of each of the internal H-Bridges (see Figure 2, 17533 Simplified Internal Block Diagram, page 2). MOTOR DRIVE POWER SUPPLY (VM1 AND VM2) The VM pins carry the main supply voltage and current into the power sections of the IC. This supply then becomes controlled and/or modulated by the IC as it delivers the power to the loads attached between the output pins. All VM pins must be connected together on the printed circuit board. GATE DRIVER CIRCUIT VOLTAGE INPUT (VG) The VG pin is the input pin for the gate drive voltage. POWER GROUND (PGND) Power ground pins. They must be tied together on the PCB. LOGIC GROUND (LGND) Logic ground pin. 17533 8 Analog Integrated Circuit Device Data Freescale Semiconductor TYPICAL APPLICATIONS INTRODUCTION TYPICAL APPLICATIONS INTRODUCTION Figure 6 shows a typical application for the 17533. When applying the gate voltage to the VG pin from an external source, be sure to connect it via a resistor equal to, or greater than, RG = VG / 0.02 . Care must be taken to provide sufficient gate-source voltage for the high-side MOSFETs when VM >> VDD (e.g., VM = 5.0 V, VDD = 3.0 V), in order to ensure full enhancement of the high-side MOSFET channels. 5.0 V 17533 VDD VG < 14 V VM OUT1A RG > VG /0.02 VG RG 0.01 F OUT1B IN1A IN1B IN2A IN2B MCU OE OUT2A OUT2B GND Figure 6. 17533 Typical Application Diagram CEMF SNUBBING TECHNIQUES PCB LAYOUT Care must be taken to protect the IC from potentially damaging CEMF spikes induced when commuting currents in inductive loads. Typical practice is to provide snubbing of voltage transients by placing a zener or a capacitor at the supply pin (VM) (see Figure 7). When designing the printed circuit board (PCB), connect sufficient capacitance between power supply and ground pins to ensure proper filtering from transients. For all highcurrent paths, use wide copper traces and shortest possible distances. 5.0 V 5.0 V 17533 VDD VM 5.0 V 5.0 V 17533 VDD VM OUT OUT OUT OUT OUT OUT OUT GND OUT GND Figure 7.
