SI4779CY Datasheet High-Side N-Channel Switch

Manufacturer: Vishay

General Description

The Si4779CY n-channel high-side switch combines a low rDS(on) MOSFET switch with a user set, pulse gate control (PGC) based current limit.

This switch is designed to protect the system power supply from overloads and short circuit conditions in applications such as USB.

The PGC based approach to the current limiter provides the additional benefit of keeping the MOSFET junction temperature within specification, thereby eliminating the need for thermal shutdown.
