DATA SHEET www.onsemi.com 3-Phase Half-Bridge Gate-Drive IC FAN73893 SOIC28, 300 mils CASE 751BM01 Description The FAN73893 is a monolithic threephase halfbridge gatedrive MARKING DIAGRAM IC designed for highvoltage, highspeed, driving MOSFETs and IGBTs operating up to +600 V. onsemis high voltage process and common mode Y&Z&2&K noisecanceling technique provide stable operation of highside FAN73893 drivers under highdV /dt noise circumstances. s An advanced levelshift circuit allows highside gate driver operation up to V = 9.8 V (typical) for V = 15 V. S BS Pin 1 The protection functions include undervoltage lockout, interlock FAN73893 = Specific Device Code function and inverter overcurrent trip with an automatic faultclear Y = Logo function. Overcurrent protection that terminates all six outputs can be &Z = Assembly Plant Code derived from an external currentsense resistor. An opendrain fault &2 = 2Digit Date Code Format &K = 2Digits Lot Run Traceability Code signal is provided to indicate that an overcurrent or undervoltage shutdown has occurred. The UVLO circuits prevent malfunction when V and V are lower than the threshold voltage. DD BS ORDERING INFORMATION Output drivers typically source and sink 350 mA and 650 mA, See detailed ordering and shipping information on page 15 of respectively which is suitable for three phase half bridge this data sheet. applications in motor drive systems.
