The MPC17533 is a monolithic Dual H-Bridge IC that is ideal in portable electronic applications for controlling stepper or Brush DC-motors for example, Camera Lens Shutters and Optical Disk drives.
MPC17533 is 2.0 ? 6.8 V dual H-bridge motor driver with enable and tri-state bridge control via a parallel MCU interface (3 and 5 V compatible logic). The IC has built-in shoot through current protection and undervoltage detector to avoid malfunction. This IC has 4 output control modes: Forward, Reverse, Brake, Tri-state (Open) and low ON-Resistance of 1.2 Ohm (max).
This MPC17533 can drive various type of micro motor with low loss via parallel drive because each section has very efficient drivers for PWM Control frequency up to 200 kHz for high speed drive and independent input/output circuitry.
