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 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.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be opera-
ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi-
tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. TA=25°C, unless otherwise specified.

Notes:
1. Mounted on 76.2 x 114.3 x 1.6mm PCB (FR-4 glass epoxy material).
2. Refer to the following standards:
JESD51-2: Integral circuits thermal test method environmental conditions - natural convection
JESD51-3: Low effective thermal conductivity test board for leaded surface mount packages
3. Do not exceed PD under any circumstances.
Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
www.DataShoepeet4raUt.icnogmconditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to absolute maximum ratings.
