modulated current control of inductive loads, the A3952S– is capable of continuous output currents to ±2 A and operating voltages to 50 V. Internal fixed off-time PWM BRAKE 1 REF 2 VBB 16 LOAD SUPPLY current-control circuitry can be used to regulate the maximum load current to a desired value. The peak load current limit is set by the 15 OUTB user’s selection of an input reference voltage and external sensing resistor. The fixed OFF-time pulse duration is set by a user-selected RC 3 14 MODE external RC timing network.
