TPS2421-1 Description

Short technical summary and product information.

The Texas Instruments TPS2421-1 is an active eFuse and hot-swap controller designed for robust power protection. It operates with an input voltage range of 3 V to 20 V and features an integrated MOSFET with a low typical on-resistance of 33 mΩ.

 

This device provides an adjustable current limit, ranging from 1.8 A to 5.5 A, along with overcurrent protection. Key features include a fault output, power good signal, and thermal shutdown for comprehensive system safety. The fault response is a latch-off mechanism, ensuring the device remains off after a fault condition.

 

With a typical quiescent current of 3.9 µA, the TPS2421-1 is suitable for power-sensitive applications. It operates across a wide temperature range of -40°C to 125°C. The device is housed in an HSOIC (DDA) package with a surface-mount design.

 

UL recognition under UL2367 (File Number E169910) is provided. The TPS2421-1 is ideal for applications requiring reliable power management and protection against overcurrent events.
