Document Number: MPC17511 Freescale Semiconductor Rev. 3.0, 10/2013 Technical Data 1.0 A 6.8 V H-Bridge Motor 17511 Driver IC The 17511 is a monolithic H-Bridge designed to be used in portable electronic applications to control small DC motors or bipolar step motors. End applications include head positioners (CDROM or disk H-BRIDGE MOTOR DRIVER IC drive), camera focus motors, and camera shutter solenoids. The 17511 can operate efficiently with supply voltages as low as 2.0 V to as high as 6.8 V. Its low R H-Bridge output MOSFETs DS(ON) (0.46 typical) can provide continuos motor drive currents of 1.0 A and handle peak currents up to 3.0 A. It is easily interfaced to low-cost MCUs via parallel 3.0 V or 5.0 V compatible logic. The device can be pulse width modulated (PWMed) at up to 200 kHz. This device contains an integrated charge pump and level shifter (for gate drive voltages), integrated shoot-through current protection EV SUFFIX) EP SUFFIX 98ASA10614D 98ARL10577D (cross-conduction suppression logic and timing), and undervoltage 24-PIN QFN 16-Pin VMFP detection and shutdown circuitry. The 17511 has four operating modes: Forward, Reverse, Brake, and Tri-state (high-impedance).
