M81738FP
1200V HIGH VOLTAGE HALF BRIDGE DRIVER
DESCRIPTION
M81738FP is 1200V high voltage Power MOSFET and IGBT
module driver for half bridge applications.
FEATURES
●Floating supply voltage up to 1200V
● Low quiescent power supply current
● Separate sink and source current output up to ±1A (typ)
● Active Miller effect clamp NMOS with sink current
up to 1A (typ)
● Input noise filters (HIN,LIN,FO_RST,FO)
● Over-current detection and output shutdown
● High side under voltage lockout
● FO pin which can input and output Fault signals to
communicate with controllers and synchronize the shut down
with other phases
● Active clamp (power supply surge clamp)
● 24pin SSOP-Lead package
APPLICATIONS
Power MOSFET and IGBT gate driver for Inverter
or general purpose.
