**Designed for bidirectional pulse-width 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 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.**
With the ENABLE input held low, the PHASE input controls load current polarity
by selecting the appropriate source and sink driver pair. The MODE input
determines whether the PWM current-control circuitry operates in a slow
current-decay mode (only the selected sink driver switching) or in a fast
current-decay mode (selected source and sink switching). A user-selectable
blanking window prevents false triggering of the PWM current control
circuitry. With the ENABLE input held high, all output drivers are disabled. A
sleep mode is provided to reduce power consumption when inactive.
When a logic low is applied to the BRAKE input, the braking function is
enabled. This overrides ENABLE and PHASE to turn OFF both source drivers and
turn ON both sink drivers. The brake function can be safely used to
dynamically brake brush dc motors.
The A3952S– is supplied in a choice of four power packages. In all package
styles, the batwing/power tab is at ground potential and needs no isolation.
These devices are also available for operation from -40°C to +125°C. To order,
change the suffix from S– to K–
