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.
