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

(0.46

Ω 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 (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).
