3968 ADVANCE INFORMATION (subject to change without notice) September 3, 1999 DUAL FULL-BRIDGE PWM MOTOR DRIVER WITH BRAKE The A3968SA and A3968SLB are designed to bidirectionally control two dc motors.

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 se
