... DUAL FULL-BRIDGE PWM MOTOR DRIVER FUNCTIONAL DESCRIPTION Internal PWM Current Control. The A3964SB and A3964SLB contain a fixed off-time pulse-width modulated (PWM) current-control circuit that can be used to limit the load current to a desired value. The peak value of the current limiting ( set by the selection of an external ...
