3966 General Description

Internal PWM Current Control. The A3966SA and A3966SLB dual H-bridges are designed to drive both windings of a bipolar stepper motor. Load current can be controlled in each motor winding by an internal fixedfrequency PWM control circuit. The current-control circuitry works as follows: when the outpu.
