Description
The FAN7361/FAN7362, a monolithic high-side gate
drive IC, can drive MOSFETs and IGBTs that operate up
to +600V. Fairchild’s high-voltage process and common-
mode noise canceling techniques provide stable opera-
tion 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
=-9.8V(typ.) for V
BS
=15V.
The UVLO circuit prevents malfunction when V
BS
is
lower than the specified threshold voltage. Output drivers
typically source/sink 250mA/500mA, respectively, which
is suitable for fluorescent lamp ballast, PDP scan driver,
motor control, and so on.

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. T

under any circumstances.
Recommended Operating Conditions
The Recommended Operating Conditions table defines the conditions for actual device operation. Recommended
operating conditions are specified to ensure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to Absolute Maximum Ratings.
