FAN7385 Datasheet, PDF (6/15 Pages) Fairchild Semiconductor – Dual-Channel High-Side Gate-Drive IC

Electrical Characteristics
V_BIAS (V_DD, V_BS1, V_BS2) = 15.0V, T_A = 25°C, unless otherwise specified. The V_IN and I_IN parameters are referenced to
GND. The V_O and I_O parameters are referenced to V_S1 and V_S2 and are applicable to the respective outputs HO1 and
HO2.
