Overview

Data Sheet 29319.
25A† 3966 A3966SLB OUT1A PHASE 1 ENABLE 1 GROUND SENSE1 OUT 1B LOAD SUPPLY REFERENCE 1 V 2 3 4 5 6 7 8 V V BB VCC RC LOGIC LOGIC BB DUAL FULL-BRIDGE PWM MOTOR DRIVER The A3966SA and A3966SLB are designed to drive both windings of a two-phase bipolar stepper motor.
Each device includes two H-bridges capable of continuous output currents of ±650 mA and operating voltages to 30 V.
Motor winding current can be controlled by the internal fixed-frequency, pulse-width modulated (PWM), current-control circuitry.
The peak load current limit is set by the user’s selection of a reference voltage and current-sensing resistors.
Except for package style and pinout, the two devices are i...
