FAN7389

3-Phase Half-Bridge Gate-Drive IC

Fairchild Semiconductor 

Electrical Characteristics

VBIAS (VDD, VBS1,2,3) = 15.0 V and TA = 25°C unless otherwise specified. The VIN and IIN parameters are referenced to

COM and are applicable to all six channels. The VO and IO parameters are referenced to VS1,2,3 and COM and are

applicable to the respective output leads: HO1,2,3 and LO1,2,3. The VDDUV parameters are referenced to COM. The

VBSUV parameters are referenced to VS1,2,3.
