The MPC17511 is a monolithic H-Bridge that is ideal in portable electronic applications to control various micro DC-motors such as Single Lense Cameras and Optical Disc Drives (MO, DVD, CD etc).
MPC17511 is 2.0 V to 6.8 V H-bridge motor driver with enable and tri-state bridge control and an additional output for controlling an external MOSFET via a parallel MCU interface 3.0 and 5.0 V compatible logic).
The IC can drive various types of micro motors with low loss via parallel drive because each section has very efficient drivers designed for PWM Control frequency up to 200 kHz for high speed drive and independent input/output circuitry.
The MPC17511 has Low ON-Resistance of 0.6 Ohm (max). The devices contains an integrated charge pump and level shifter for gate drive voltages, with an integrated shoot through current protection circuit and undervoltage circuit detector to avoid malfunction.
This IC has 4 output control modes: Forward, Reverse, Brake, Tri-state (Open).
