Preliminary Data Sheet  
Subject to Change without Notice  
November 4, 2005  
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.  
Package LP, 16-pin TSSOP  
with Exposed Thermal Pad  
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.
