All rights reserved. 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 m Ω 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 Figure 1. 17511A Simplified Application Diagram H-BRIDGE MOTOR DRIVER IC EV SUFFIX (PB-FREE) 98ASA10614D 16-PIN VMFP 17511A ORDERING INFORMATION Device Temperature Range (TA) Package MPC17511AEV -20°C to 65°C 16 VMFP MPC17511AEV/EL MPC17511AEP 24 QFN MPC17511AEP/R2 EP SUFFIX (PB-FREE) 98ARL10577D 24-PIN QFN VDD C1L C1H C2L C2H CRES EN GIN IN1 IN2 GND VM GOUT OUT1 OUT2 5.0V 17511A MCU Motor 5.0V |
