Both bridges are capable of sustaining 45 V and include internal pulse-width modulation (PWM) control of the output current to 1.5 A. For PWM current control, the maximum output current is determined by the user’s selection of a reference voltage and sensing resistor. Two logic-level inputs select output current limits of 0, 33%, 67%, or 100% of the maximum level. A PHASE input to each bridge determines load current direction. Active-low ENABLE...
