3935  
3-PHASE POWER MOSFET CONTROLLER  
— For Automotive Applications  
The A3935 is designed specifically for automotive applications that  
require high-power motors. Each provides six high-current gate drive  
outputs capable of driving a wide range of n-channel power MOSFETs.  
Package ED, 44-Pin PLCC  
A requirement of automotive systems is steady operation over a  
varying battery input range. The A3935 integrates a pulse-frequency  
modulated boost converter to create a constant supply voltage for  
driving the external MOSFETs. Bootstrap capacitors are utilized to  
provide the above battery supply voltage required for n-channel FETs.  
Package JP, 48-Pin LQFP  
Package LQ, 36-Pin SOIC  
Direct control of each gate output is possible via six TTL-compat-  
ible inputs. A differential amplifier is integrated to allow accurate  
measurement of the current in the three-phase bridge.  
Diagnostic outputs can be continuously monitored to protect the  
driver from short-to-battery, short-to-supply, bridge-open, and battery  
under/overvoltage conditions. Additional protection features include  
dead-time, VDD undervoltage, and thermal shutdown.  
The A3935 is supplied in a choice of three packages, a 44-lead  
PLCC with copper batwing tabs (suffix ED), a 48-lead low profile QFP  
with exposed thermal pad (suffix JP), and a 36-lead 0.8 mm pitch SOIC  
(suffix LQ).
