Description

Designed for bidirectional pulse width modulated (PWM) current control of inductive loads, the A4973 is capable of continuous output currents to ±1.5 A and operating voltages to 50 V. Internal fixed off-time PWM 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 user’s selection of an input reference voltage and external sensing resistor. The fixed off-time pulse duration is set by a user- selected external RC timing network. Internal circuit protection includes thermal shutdown with hysteresis, transient-suppression diodes, and crossover current protection. Special power-up sequencing is not required.

Features and Benefits

▪ Internal PWM current control

▪ Fast and slow current-decay modes

▪ Sleep (low current consumption) mode

▪ Internal transient-suppression diodes

▪ Internal thermal shutdown circuitry

▪ Crossover current and UVLO protection
