0.4 A Dual H-Bridge Motor
Driver IC
IC, ideal for portable electronic applications containing bipolar
stepper motors or brush DC motors such as those used in camera
lenses and shutters.
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.
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.
Features
The 17C724 is a compact monolithic dual channel H-Bridge power
The 17C724 can operate efficiently with supply voltages from 2.7
The 17C724 has four output control modes: Forward, Reverse,
• Manufactured in SMOS7 Process Technology
• Built-In 2-Channel H-Bridge Driver
