TPS2421-2DDAR Description

Short technical summary and product information.

The Texas Instruments TPS2421-2DDAR is an integrated circuit designed for hot swap applications, functioning as an eFuse and hot swap controller. It supports an input voltage range from 3V to 20V, with a maximum continuous voltage rating of 25V. The device offers an adjustable current limit, configurable from 1.8A to a maximum of 5.5A. Key features include auto-retry, thermal shutdown, overcurrent protection, and a power good signal.

 

This controller is housed in an 8-pin SO PowerPad package, suitable for surface mounting. It operates reliably within a temperature range of -40°C to 125°C. The TPS2421-2DDAR is recognized under UL2367, indicating compliance with relevant safety standards. Its programmable features, such as current limit and fault timeout, allow for flexible system design.

 

With an integrated pass MOSFET and a typical on-resistance of 33mΩ, this device is well-suited for general-purpose power management and protection circuits. The low quiescent current, typically 3.9µA, ensures minimal power consumption in standby modes.
