DESCRIPTION

· The MPC17511 is a monolithic H-Bridge motor driver IC designed for portable electronic applications.

· It controls micro DC-motors in Single Lens Reflex Cameras and Optical Disc Drives (MO, DVD, and CD).

· Features a 6.8 V H-Bridge with enable and tri-state bridge control.

· Includes an output for controlling an external MOSFET via a parallel MCU interface (3.0 V and 5.0 V compatible logic).

· Operates with a low "ON" resistance of 0.6 Ω (max) and supports PWM control frequency up to 200 kHz.

· Integrated charge pump, level shifter, shoot through current protection, and undervoltage circuit detector.

FEATURES

· Easy MCU interfacing and control of a single H-Bridge.

· Undervoltage detection to prevent erratic operation.

· High PWM rate for enhanced motor control.

· Output protected H-Bridge operation to 6.8 V @ 1.0 A cont. PWM to 200 kHz.

· Low profile package for portable designs.

· Integral charge pump for a simpler system.

· TSWITCH output for driving an external MOSFET.

· Low quiescent current and reduced design time.

APPLICATIONS

· Portable Electronics.

· Single Lens Camera.

· Optical Disc Drive (MO, DVD, and CD).
