17517 Simplified Application Diagram

1.0 A 6.8 V Dual Motor Driver IC

The 17517 is a monolithic triple totem-pole-output power IC designed to be

used in portable electronic applications to control small DC motors and

solenoids. The 17517 can operate efficiently with supply voltages as low as

typical) can provide continuos drive currents of 1.0 A and handle peak currents

up to 3.0 A. It is easily interfaced to low-cost MCUs via parallel 3.0 V- or 5.0 V-

compatible logic. The device can be pulse width modulated (PWM-ed) at up to

200 kHz.

The 17517 can drive two motors in two directions one at a time or drive one

motor in two directions and one solenoid with synchronous rectification of

freewheeling currents one at a time. Two-motor operation is accomplished by

hooking one motor between OUTA and OUTB and hooking the other motor

between OUTB and OUTC. Motor plus solenoid operation is accomplished by

hooking a motor between OUTA and OUTB and a solenoid between OUTC

and GND.

This device contains an integrated charge pump and level shifter (for gate

drive voltages), integrated shoot-through current protection (cross-conduction

suppression logic and timing), and undervoltage detection and shutdown

circuitry.

The 17517 has four operating modes: Forward, Reverse, Brake, and

Tri-Stated (High Impedance).
