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.

onsemi’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.
