Description
The A3951SB is an electronic component model designed for bidirectional pulse-width modulated current control of inductive loads. It is capable of continuous output currents to ±2 A and operating voltages to 50 V. The A3951SB is an improved replacement for the UDN2953B and is recommended for new system designs. It features internal fixed off-time PWM current-control circuitry and can regulate the maximum load current to a desired value. The peak load current limit is set by the user's selection of an input reference voltage and external sensing resistor. It also has internal circuit protection, including thermal shutdown with hysteresis, transient suppression diodes, and crossover-current protection.
