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 for VBS Output In-phase with Input Signal 8-SOP
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 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
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. TA=25C, unless otherwise specified.
