Freescale Semiconductor, Inc. Freescale Semiconductor, Inc... POWER ICs MPC17511 FACT SHEET 17511 0.46 Ω (TYP) H-BRIDGE MOTOR DRIVER IC The 17511 is a monolithic H-Bridge that is ideal in portable electronic applications to control various micro DC-motors found in Single Lens Reflex Cameras and Optical Disc Drives (MO, DVD, and CD). APPLICATIONS • Portable Electronics • Single Lens Camera • Optical Disc Drive (MO, DVD, and CD) The 17511 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 (3.0 V and 5.0 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 highspeed drive and independent input/output circuitry. The 17511 has a low “ON” resistance of 0.6 Ω (max). 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 Tri-state (Open).
