Both bridges are capable of sustaining 45 V and include internal pulse-width modulation (PWM) control of the output current to 750 mA. The outputs have been optimized for a low output saturation voltage drop (less than 1.8 V total source plus sink at 500 mA). For PWM current control, the maximum output current is determined by the user’s selection of a reference voltage and sensing resistor.
