3-Phase Half-Bridge Gate-Drive IC FAN73895 Description The FAN73895 is a monolithic threephase halfbridge gatedrive www.onsemi.com IC designed for highvoltage, highspeed, driving MOSFETs and IGBTs operating up to +600 V. ON Semiconductors highvoltage process and commonmode noisecanceling technique provide stable operation of highside drivers under highdv/dt noise circumstances. An advanced levelshift circuit allows highside gate driver operation up to V = 9.8 V (typical) for V = 15 V. S BS SOIC28, 300 mils The protection functions include undervoltage lockout and inverter CASE 751BM01 overcurrent trip with an automatic faultclear function. Overcurrent protection that terminates all six outputs can be derived from an MARKING DIAGRAM external currentsense resistor. An opendrain fault signal is provided to indicate that an overcurrent or undervoltage shutdown has occurred. The UVLO circuits prevent malfunction when V and V DD BS are lower than the threshold voltage. Y&Z&2&K FAN73895 Output drivers typically source and sink 350 mA and 650 mA, respectively which is suitable for three phase half bridge applications in motor drive systems.
