Designed for bidirectional pulse-width modulated (PWM) current control of inductive loads, the A3953S— is capable of continuous output currents to ±1.
3 A and operating
voltages to 50 V.
Internal fixed off-time PWM currentcontrol 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 externa...
