Freescale Semiconductor
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.
