FAN7389 Datasheet, PDF (6/18 Pages) Fairchild Semiconductor – 3-Phase Half-Bridge Gate-Drive IC

Electrical Characteristics
VBIAS (VDD, VBS1,2,3) = 15.0V 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.
