Description
The FAN73901 is a monolithic high- and low-side gate-
drive IC, which can drive high-speed MOSFETs and
IGBTs that operate up to +600V. It has a buffered output
stage with all NMOS transistors designed for high pulse
current driving capability and minimum cross-conduction.
Fairchildâs high-voltage process and common-mode
noise canceling techniques provide stable operation of
the high-side driver under high dv/dt noise circum-
stances. An advanced level-shift circuit offers high-side
gate driver operation up to VS=-9.8V (typical) for
VBS=15V.
The UVLO circuit prevents malfunction when VDD and
VBS are lower than the specified threshold voltage.
The high current and low output voltage drop feature
make FAN73901 suitable for the switching power supply,
motor driver, and high-power DC-DC converter
applications.
