A3941  
Automotive Full Bridge MOSFET Driver  
Features and Benefits  
Description  
High current gate drive for N-channel MOSFET full bridge  
High-side or low-side PWM switching  
Charge pump for low supply voltage operation  
Top-off charge pump for 100% PWM  
Cross-conduction protection with adjustable dead time  
5.5 to 50 V supply voltage range  
The A3941 is a full-bridge controller for use with external  
N-channel power MOSFETs and is specifically designed for  
automotiveapplicationswithhigh-powerinductiveloads,such  
as brush DC motors.  
A unique charge pump regulator provides full (>10 V) gate  
drive for battery voltages down to 7 V and allows the A3941  
to operate with a reduced gate drive, down to 5.5 V.  
Integrated 5 V regulator  
Diagnostics output  
Low current sleep mode  
A bootstrap capacitor is used to provide the above-battery  
supply voltage required for N-channel MOSFETs.An internal  
charge pump for the high-side drive allows DC (100% duty  
cycle) operation.  
Package: 28-pin TSSOP with exposed  
thermal pad (suffix LP)  
The full bridge can be driven in fast or slow decay modes using  
diode or synchronous rectification. In the slow decay mode,  
current recirculation can be through the high-side or the low-  
side FETs. The power FETs are protected from shoot-through  
by resistor adjustable dead time.  
Integrated diagnostics provide indication of undervoltage,  
overtemperature, and power bridge faults, and can be  
configured to protect the power MOSFETs under most short  
circuit conditions.  
TheA3941 is supplied in a 28-pin TSSOPpower package with  
an exposed thermal pad (suffix LP). This package is lead (Pb)  
free, with 100% matte-tin leadframe plating.
