Dual H-Bridge Motor Driver 2-8.6 V 1.4 A 200 kHz

Overview

The NXP^® MPC17531A is a monolithic dual H-Bridge power IC ideal for portable electronic applications containing bipolar step motors and/or brush DC-motors, such as cameras and disk drive head positioners.

Operates from 2.0 V to 8.6 V using the internal charge pump, with independent control of each H-Bridge via parallel MCU interface
Features built-in shoot-through current protection and an undervoltage shutdown function
Has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance)
Efficiently drives many types of micromotors with low power dissipation owing to its low output resistance and high output slew rates

Features

Low Total RDS(ON) 0.8 Ω (Typ), 1.2 Ω (Max) @ 25°C
Output Current 0.7 A (DC)
Shoot-Through Current Protection Circuit
PWM Control Input Frequency up to 200 kHz
Built-In Charge Pump Circuit
Low Power Consumption
Undervoltage Detection and Shutdown Circuit
Power Save Mode with Current Draw ≤ 2.0 µA
Pb-Free Packaging Designated by Suffix Codes EV and EP
