TPS2421-2DDA Description

Short technical summary and product information.

The Texas Instruments TPS2421-2DDA is an integrated circuit designed for hot swap applications, providing robust power protection. It supports an input voltage range from 3V to 20V, with an absolute maximum continuous voltage of 25V.

 

This device features an adjustable current limit, ranging from 1.8A to a maximum of 5.5A, and a typical on-resistance of 33mΩ. Key protection features include auto-retry functionality, thermal limit, and undervoltage lockout (UVLO). The device also offers programmable features for current limit and fault timeout.

 

Packaged in an 8-pin SO PowerPad (HSOIC DDA), the TPS2421-2DDA is suitable for surface mount applications. It operates within a temperature range of -40°C to 125°C, making it suitable for various environmental conditions. The typical quiescent current is 3.9mA, with a maximum of 5mA.

 

This hot swap controller is ideal for general-purpose applications requiring reliable power management and protection against overcurrent and thermal events.
