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 +600 V. 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
S
=-9.8 V (typical) for
V
BS
=15 V.
The UVLO circuit prevents malfunction when V
DD
and
V
BS
are lower than the specified threshold voltage.
The high current and low output voltage drop features
mak sFAN73901 suitable for switching power supply,
motor driver, and high-power DC-DC converter
applications.
