Target Applications

Overview

•t Portable electronics

The MPC17511 is a monolithic H-bridge that is ideal in portable electronic applications

•t Single lens camera

to control various micro DC-motors found in Single Lens Reflex Cameras and Optical

•t Optical disc drive (MO, DVD and CD)

Disc Drives (MO, DVD and CD). The MPC17511 is a 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 V and 5 V compatible logic). The IC can drive
various types of micro motors with low loss via parallel drive. The part uses very efficient
drivers designed for PWM control frequency up to 200 kHz for high-speed drive and
independent input/output circuitry.
The MPC17511 has a low “ON” resistance of 0.46 Ω (typ). The output devices use an
integrated charge pump and level shifter for gate drive voltages, with integrated shoot
through current protection circuit and undervoltage circuit detector. The bridge operates
in four output control modes: Forward, Reverse, Brake and Tristate (Open).
