描述 Description

The NXP® MPC17C724 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.
Operates 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
Easily interfaced to low-cost MCUs via parallel 3.0 V- or 5.0 V-compatible logic
Built-in shoot-through current protection circuit and undervoltage detector to avoid malfunction
The H-bridge outputs are designed to be independently PWM'ed at up to 200 kHz for speed/torque and current control
