Overview

Freescale Semiconductor Technical Data 0.
4 A Dual H-Bridge Motor Driver IC Document Number: MPC17C724 Rev 3.
0, 9/2014 17C724 The 17C724 is a SMARTMOS compact monolithic dual channel HBridge 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 RDS(on) of 1.
0 .
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 PWMed at up to 200 kHz for speed/ torque and current control.
