Technical Data

0.4 A Dual H-Bridge Motor

Driver IC

17C724

The 17C724 is a compact monolithic dual channel H-Bridge power

IC, ideal for portable electronic applications containing bipolar

stepper motors or brush DC motors such as those used in camera

lenses and shutters.

MOTOR DRIVER

The 17C724 can operate efficiently with supply voltages from 2.7

V to 5.5 V and can provide continuous motor drive currents of 0.4 A

with low RDS(ON) of 1.0 Ω. It is easily interfaced to low-cost MCUs

via parallel 3.0 V- or 5.0 V-compatible logic and has built-in shoot-

through current protection circuit and undervoltage detector to avoid

malfunction.

The 17C724 has four output control modes: Forward, Reverse,

Brake, and Tri-State (High Impedance). The H-bridge outputs are

designed to be independently PWM’ed at up to 200 kHz for speed/

torque and current control.
