MPC17531ATEJ数据手册恩XP中文资料规格书

描述 Description

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
