Features - - - - - - - - - High Current Output: 1.0A Source and 2.0A Sink Protection against Overcurrent and Short circuit CMOS patible Input and Fault Status Indicator Programmable Fault-Out Duration Time Built in Slow Turn-off Circuit Under Fault Condition Undervoltage Lockout Optimized for IGBTs Negative Gate Drive Capability Suitable for Integration in Power Modules -40 to 105°C Operating Temperature Description The FAN8800 is a monolithic integrated circuit designed for driving single IGBT with De-saturation and undervoltage protection. It is suitable for driving discrete and module IGBTs, and further, it offers a cost effective solution for driving power MOSFETs. The integrated fault feedback notifies the controller when the IGBT is shutdown due to a De-saturation or a over current condition. 8-DIP ETC. DRIVE IC Typical Applications - Gate drive for single insulated gate bipolar TR - Gate drive for single MOSFET Rev. 1.0.0 ©2000 Fairchild Semiconductor Corporation FAN8800 (KA3162) Pin Assignments TDUR DESAT FAULT IN 3 6 VCC Vee ( Top View ) ETC.

FAULT changes from a logic low state to a logic high output when a fault condition is detected. De-saturation voltage input. When the voltage on DESAT exceeds an internal reference voltage of 6.5v while the IGBT is on, FAULT output is changed from a logic low state to a logic high state.
