A3935  
3-Phase Power MOSFET Controller for Automotive Applications  
Features and Benefits  
Description  
Drives wide range of N-channel MOSFETs in 3-phase bridges  
PFM boost converter for use with low-voltage battery supplies  
Internal LDO regulator for gate-driver supply  
Bootstrap circuits for high-side gate drivers  
Current monitor output  
TheA3935isdesignedspecificallyforautomotiveapplications  
thatrequirehigh-powermotors.Eachprovidessixhigh-current  
gatedriveoutputscapableofdrivingawiderangeofN-channel  
power MOSFETs.  
Arequirement 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.  
Adjustable battery overvoltage detection  
Diagnostic outputs  
Motor lead short-to-battery, short-to-ground, and bridge-  
open protection  
Undervoltage protection  
–40°C to 150°C T operation  
J
Thermal shutdown  
Direct control of each gate output is possible via six TTL-  
compatible inputs. A differential amplifier is integrated to  
allow accurate measurement of the current in the three-phase  
bridge.  
Package 36-pin QSOP (LQ):  
Diagnostic outputs can be continuously monitored to protect  
the driver from short-to-battery, short-to-supply, bridge-open,  
andbatteryunder/overvoltageconditions.Additionalprotection  
features include dead-time, VDD undervoltage, and thermal  
shutdown.  
TheA3935issuppliedina36-lead0.8mmpitchQSOP(package  
LQ, similar to SOICW).The lead (Pb) free variants (suffix –T)  
have 100% matte tin leadframe plating.
