AP2301SN-7

Power Distribution Switches, Load Drivers Overview

The AP2301SN-7 is a single-channel P-channel power switch IC designed for USB load switching applications. It operates within a voltage range of 2.7V to 5.5V and supports a maximum output current of 2A. The device features a typical on-resistance of 70 milliohms and utilizes a U-DFN2020-6 surface-mount package. Key protection mechanisms include fixed current limiting, over-temperature shutdown, reverse current blocking, and under-voltage lockout (UVLO). It offers non-inverted input control with load release and status flag capabilities, functioning reliably across an operating temperature range of -40°C to +85°C.
