Description
The A3956LB is an electronic component designed for bidirectional pulse-width modulated current control of inductive loads. It is capable of continuous output currents up to ±2A and operating voltages up to 50V. The A3956LB features internal fixed off-time PWM current-control circuitry that allows regulation of 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. The A3956LB also includes internal circuit protection such as thermal shutdown with hysteresis, transient suppression diodes, and crossover-current protection. It is an improved replacement for the UDN2953B and UDN2954W and is recommended for new system designs.
