1 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! & V BS Supply Range from 10V to 20V! UVLO Function for V BS! Output In-phase with Input Signal! 8-SOP Applications! PDP Scan Driver! Motor Control! SMPS! Electronic Ballast Description November 2009 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 =-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. 8-SOP Ordering Information Part Number FAN7361M (1) FAN7361MX (1) FAN7362M (1) FAN7362MX (1) Package Operating Temperature Range Eco Status 8-SOP -40 C ~ 125 C RoHS Packing Method Tube Tape & Reel Tube Tape & Reel Note: 1.

4 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.
