Reliable, Integrated Smart High-Side Switches

Offer Space-Savings

Reliably and safely switching high currents into grounded resistive or inductive

loads is a necessity for designers of automotive applications. Fairchild has

developed a smart high-side switch family that specifically addresses advanced

electrical load—without relying on discrete MOSFET solutions. By integrating

protection and diagnostic features, you benefit from reduced component count

and PCB complexity, as well as better system reliability.

The family includes the FDDS100H06_F085 smart high-side switch, an

N-channel power MOSFET with charge pump, ground-referenced CMOS-

compatible input and diagnostic output with integrated protection functions.

The family also offers the FDBS09H04A_F085A and FDDS10H04A_F085A

smart high-side switches, incorporating an N-channel power MOSFET device

featuring a charge pump, current controlled input and diagnostic feedback with

load current sense and integrated Smart Trench chip-on-chip technology.
