FAN7171-F085
600 V / 4 A, High-Side
Automotive Gate Driver IC
Description
The FAN7171-F085 is a monolithic high−side gate drive IC that can
drive high−speed MOSFETs and IGBTs that operate up to +600 V. It
has a buffered output stage with all NMOS transistors designed for
high pulse current driving capability and minimum cross−conduction.
ON Semiconductor’s high−voltage process and common−mode
noise-canceling techniques provide stable operation of the high−side
driver under high-dv/dt noise circumstances. An advanced level−shift
circuit offers high−side gate driver operation up to VS = −9.8 V
(typical) for VBS = 15 V.
The UVLO circuit prevents malfunction when VBS is lower than the
specified threshold voltage.
The high−current and low−output voltage-drop feature make this
device suitable for sustaining switch drivers and energy−recovery
switch drivers in automotive motor drive inverters, switching power
supplies, and high−power DC−DC converter applications.
