Freescale Semiconductor Technical Data Document Number: MPC17511A Rev. 5.0, 9/2008 1.0 A 6.8 V H-Bridge Motor Driver IC The 17511A 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 drive), camera focus motors, and camera shutter solenoids. The 17511A can operate efficiently with supply voltages as low as 2.0V to as high as 6.8V. Its low RDS(ON) H-Bridge output MOSFETs (0.46 Ω typical) can provide continuos motor drive currents of 1.0A and handle peak currents up to 3.0A. It is easily interfaced to low-cost MCUs via parallel 3.0V- or 5.0V- compatible logic. The device can be pulse width modulated (PWM-ed) at up to 200 kHz. This device contains an integrated charge pump and level shifter (for gate drive voltages), integrated shoot-through current protection (cross-conduction suppression logic and timing), and undervoltage detection and shutdown circuitry. The 17511A has four operating modes: Forward, Reverse, Brake, and Tri-Stated (High Impedance). Features 2.0V to 6.8V Continuous Operation Output Current 1.0 A(DC), 3.0A (Peak) MOSFETs < 600 mΩ RDS(ON) @ 25°C Guaranteed 3.0V/ 5.0V TTL- / CMOS-Compatible Inputs PWM Frequencies up to 200 kHz Undervoltage Shutdown Cross-Conduction Suppression Low Power Consumption Pb-Free Packaging Designated by Suffix Codes EV and EP 17511A H-BRIDGE MOTOR DRIVER IC EV SUFFIX (PB-FREE) 98ASA10614D ……
