Description

Designed for PWM (pulse width modulated) control of dc motors, the A3950 is capable of peak output currents to ±2.8 A and operating voltages to 36 V.


PHASE and ENABLE input terminals are provided for use in controlling the speed and direction of a dc motor with externally applied PWM control signals. Internal synchronous rectification control circuitry is provided to lower power dissipation during PWM operation.

Internal circuit protection includes motor lead short-to-supply / short-toground, thermal shutdown with hysteresis, undervoltage monitoring of VBB and VCP, and crossover-current protection.

The A3950 is supplied in a thin profile (<1.2 mm overall height) 16-pin TSSOP package with exposed thermal pad (package LP). It is lead (Pb) free with 100% matte tin leadframe plating.
