MPC17533数据手册恩XP中文资料规格书

描述 Description

OverviewThe NXP® MPC17533 is a monolithic dual H-Bridge IC that is ideal in portable electronic applications for controlling stepper or Brush DC-motors, such as camera lens shutters and optical disk drives.
Operates from 2.0 V to 6.8 V, with independent control of each H-Bridge via the parallel MCU interface (3.0 V and 5.0 V compatible logic)
Built-in shoot through current protection and undervoltage detector to avoid malfunction
Four output control modes: Forward, Reverse, Brake, Tri-state (Open) and low ON-Resistance of 1.2 Ohm (max)
Can drive various type of micro motor with low loss via parallel drive because each section has very efficient drivers for PWM Control for high speed drive
