Smart high-side switches from Fairchild for automotive applications

Fairchild Semiconductor has developed a smart high-side switch family that addresses advanced electrical load control in automotive body electronics. The family provides an alternative to discrete MOSFET solutions that integrates protection and diagnostic features in order to reduce component count and PCB complexity. This family also offers better system reliability.

The FDDS100H06_F085 smart high-side switch is an N-channel power MOSFET with charge pump, ground referenced CMOS compatible input and diagnostic output with integrated protection functions. The diagnostic feedback capability of the FDDS100H06_F085 provides system control options to minimize impact under various fault conditions.

The FDBS09H04A_F085A and FDDS10H04A_F085A are 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.
