Advance Information

1.0 A 6.8 V Dual Motor Driver IC

17517

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 2.0 V to as high as 6.8 V. Its low

DUAL MOTOR DRIVER

R_DS(ON)totem-pole output MOSFETs (0.46 Ω typical) can provide

continuous 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.
