FAN7361, FAN7362 High-Side Gate Driver
Features
Floating Channel Designed for Bootstrap Operation to +600V Typically 250mA/500mA Sourcing/Sinking Current Driving Capability Common-Mode dv/dt Noise Canceling Circuit VCC & VBS Supply Range from 10V to 20V UVLO Function Output In-phase with Input 8-SOP
Description
The FAN7361/FAN7362, a monolithic high-side gate driver IC, can drive MOSFETs and IGBTs that operate up to +600V. Fairchild's high-voltage process and commonmode noise canceling techniques provide stable operation of the high-side driver under high dv/dt noise circumstances. An advanced level shift circuit offers high-side gate driver operation up to VS=-9.8V(typ.) for VBS=15V. The UVLO circuit prevents malfunction when VBS 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
The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The "Recommended Operating Conditions" table defines the conditions for actual device operation.
