September 2005
High-Side Gate Driver
FAN7361, FAN7362
Features
鈥?Floating Channel Designed for Bootstrap Operation to
+600V.
鈥?Typically 250mA/500mA Sourcing/Sinking Current Driving
Capability
鈥?Common-Mode dv/dt Noise Canceling Circuit
鈥?VCC & VBS Supply Range from 10V to 20V
鈥?UVLO Function
鈥?Output In-phase with Input
Description
The FAN7361
/
2, a monolithic high-side gate driver IC, can drive
MOSFETs and IGBTs which operate up to +600V. Fairchild鈥檚
high voltage process and common-mode noise canceling tech-
nique provides stable operation of the high-side driver under
high dv/dt noise circumstances. An advanced level short circuit
allows 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 fluores-
cent lamp ballast, PDP scan driver, motor control, and so on.
Typical Applications
鈥?Fluorescent Lamp Ballast
鈥?PDP Scan Driver
鈥?Motor Control
