A3950
DMOS Full-Bridge Motor Driver
Designed for PWM (pulse width modulated) control of dc motors, the
A3950 is capable of peak output currents to ±2.8 A and operating volt-
ages to 36 V.
PHASE and ENABLE input terminals are provided for use in control-
ling 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-to-
ground, thermal shutdown with hysteresis, undervoltage monitoring of
V
BB
and V
CP
, 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.
