A3950  
DMOS Full-Bridge Motor Driver  
Features and Benefits  
Low RDS(on) outputs  
Overcurrent protection  
Motor lead short-to-supply protection  
Short-to-ground protection  
Sleep function  
Synchronous rectification  
Diagnostic output  
Description  
Designed for PWM (pulse width modulated) control of dc  
motors, theA3950 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  
controllingthespeedanddirectionofadcmotorwithexternally  
appliedPWMcontrolsignals.Internalsynchronousrectification  
control circuitry is provided to lower power dissipation during  
PWM operation.  
Internal undervoltage lockout (UVLO)  
Crossover-current protection  
Internal circuit protection includes motor lead short-to-  
supply/short-to-ground, thermal shutdown with hysteresis,  
undervoltagemonitoringofVBB andVCP,andcrossover-current  
protection.  
Packages:  
TheA3950issuppliedinathinprofile(<1.2mmoverallheight)  
16 pinTSSOPpackage (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.  
Package LP, 16 pin TSSOP  
with Exposed Thermal Pad  
Package EU, 16 pin QFN  
with Exposed Thermal Pad
