| FAN7361/FAN7362 High-Side Gate Driver September 2005 High-Side Gate Driver FAN7361, FAN7362 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 Description The FAN7361/2, a monolithic high-side gate driver IC, can drive MOSFETs and IGBTs which operate up to +600V. Fairchild's high voltage process and common-mode noise canceling technique 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 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. Typical Applications * Fluorescent Lamp Ballast * PDP Scan Driver * Motor Control 8SOIC 1 (c)2005 Fairchild Semiconductor Corporation 1 www.fairchildsemi.com FAN7361,FAN7362 Rev. 1.0.0 FAN7361/FAN7362 High-Side Gate Driver Block Diagrams HIGH-SIDE DRIVER 8 VB VCC 3 LEVEL SHIFTER NOISE CANCELLER UVLO RR S DRIVER 7 HO 6 VS Q IN 2 SHORT PULSE GENERATOR GND 4 Pin Assignments NC 1 8 VB FAN7361/2 IN 2 VCC 3 GND 4 7 HO FAN7361/7362 6 VS 5 NC Pin Definitions Pine Number 1 2 3 4 5 6 7 8 GND NC VS HO VB Pin Name NC IN Vcc I/O I I I I O I No Connection Pin Function Description Logic Input for High Side Gate Driver Output Supply Voltage Logic Ground No Connection High Voltage Floating Supply Return High Side Driver Output High Side Floating Supply 2 FAN7361,FAN7362 Rev. 1.0.0 www.fairchildsemi.com FAN7361/FAN7362 High-Side Gate Driver Absolute Maximum Ratings Parameter Highg side offset voltage High side floating supply voltage High side floating output voltage HO Logic fixed supply voltage Logic input voltage (IN) Allowable offset voltage slew rate Power dissipation Thermal resistance, junction to ambient Junction temperature Storage temperature Notes: 1.Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur.
