Product Overview

The A3968SLBTR-T is a dual full-bridge PWM Motor Driver includes two full-bridges capable of continuous output currents of ±650mA and operating voltages to 30V. 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 user selection of a reference voltage and current-sensing resistors. The fixed-frequency pulse duration is set by user-selected external RC timing network. The capacitor in the RC timing network also determines user-selectable blanking window that prevents false triggering of the PWM current-control circuitry during switching transitions. To reduce on-chip power dissipation, the full-bridge power outputs have been optimized for low saturation voltages. The sink drivers feature the Allegro™ patented Satlington® output structure. The Satlington outputs combine the low voltage drop of a saturated transistor and the high peak current capability of a Darlington.
