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-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 (LP), and a very thin (0.75 mm nominal
height) QFN package. Both packages provide an exposed pad
for enhanced thermal dissipation, and are lead (Pb) free with
100% matte tin leadframe plating.
Packages:
Package LP, 16 pin TSSOP
with Exposed Thermal Pad
Package EU, 16 pin QFN
