Analog, Mixed-Signal and Power Management MPC17511 1.0 A 6.8 V H-Bridge Motor Driver IC Target Applications Overview • Portable electronics The MPC17511 is a monolithic H-bridge that is ideal in portable electronic applications • Single lens camera to control various micro DC-motors found in Single Lens Reflex Cameras and Optical • 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).
