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

▪ 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.

LQ, similar to SOICW).The lead (Pb) free variants (suffix –T)

have 100% matte tin leadframe plating.
