FPF2123 Description

Short technical summary and product information.

The FPF2123 from ON Semiconductor is a general-purpose power distribution switch designed for efficient power management.

 

This component features a P-channel output configuration and a high-side switch type, capable of handling up to 1.5A of current. It includes essential fault protection mechanisms such as current limiting, over-temperature protection, reverse current protection, and undervoltage lockout (UVLO). The switch type is general purpose with an On/Off interface.

 

Designed for surface mounting, the FPF2123 is supplied in a compact SOT-23-5 package (also referred to as SC-74A, SOT-753). It operates within a temperature range of -40°C to 85°C (TA), making it suitable for various environmental conditions. The Rds On is typically 125mOhm, and it includes an auto-restart feature.

 

This power distribution switch is suitable for applications requiring reliable power control and protection.
