MPC17529: Dual H-Bridge, Motor Driver, 2-6.8 V, 1.4 A, 200 kHz

Overview

The NXP^® MPC17529 is a monolithic dual H-Bridge IC that is ideal for portable electronic applications to control bipolar stepper motors and Brush DC-motors, such as in camera lens shutters, optical disk drives and other head positioners.

Enable and tri-state bridge control via a parallel MCU interface (3 and 5 V compatible logic)
On-board charge pump, and built-in shoot through current protection and undervoltage detector to avoid malfunction
Can drive various type of micro motor with low loss via parallel drive because each section has efficient drivers for PWM control frequency up to 200kHz for high speed drive and independent input/output circuitry

Features

Low RDS(ON) 0.7 Ohm(typ)
Output current 700 mA (DC), 1.4 A (Peak)
Shoot through current protection circuit
PWM control input frequency 200 kHz
Charge pump circuit
Four output control modes: Forward, Reverse, Brake, Tri-state (Open) and low ON Resistance of 1.2 Ohm(max)
