SI4779CY Datasheet (Vishay Siliconix) - High-Side N-Channel Switch

SI4779CY, High-Side N-Channel Switch

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 th
