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.
Fairchild’s 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 V
V
=15V.
BS
The UVLO circuit prevents malfunction when V
V
are lower than the specified threshold voltage.
BS
The high current and low output voltage drop feature
make FAN73901 suitable for the switching power supply,
motor
driver,
and
applications.
