AP2820FMM-G1

Power Distribution Switches, Load Drivers Overview

The AP2820FMM-G1 is a high-side power distribution switch manufactured by Diodes Incorporated, designed for USB power switching applications. It integrates an N-Channel MOSFET with a charge pump and protection circuits in an 8-MSOP package. The device operates within a load voltage range of 2.7V to 5.5V and supports a maximum output current of 2.5A. Key electrical characteristics include a typical on-resistance of 60 milliohms and a non-inverting open/switch interface. It functions without a separate supply voltage and includes fixed current limiting, overtemperature, reverse current, and UVLO protections.
