NCP380HSN05AAT1G Description

Short technical summary and product information.

The NCP380HSN05AAT1G is a high-side P-channel power distribution switch from On Semiconductor designed for general-purpose power management applications. It operates over a supply voltage range of 2.5V to 5.5V and features a user-adjustable current limit from 500mA to 2.1A, with a fixed current limit of 500mA by default.

 

The device integrates a 70mOhm typical Rds(on) P-channel MOSFET output, providing efficient power delivery. It includes fault protection features such as current limiting and undervoltage lockout (UVLO), as well as a status flag output for fault indication. The switch is slew-rate controlled to minimize inrush current during turn-on.

 

The NCP380HSN05AAT1G is offered in a 5-pin TSOP package and is rated for an ambient operating temperature range of -40°C to 85°C, with a junction temperature range of -40°C to 125°C. It is suitable for USB ports, hot-swap applications, and general-purpose power distribution in consumer and industrial electronics.
