Technical Data
0.4 A Dual H-Bridge Motor
Driver IC
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.
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 R DS(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.
