描述 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.
