102a 3935 Package ED, 44-Pin PLCC 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.
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.
Direct control of each ga...
