TPS25921AD Description

Short technical summary and product information.

The Texas Instruments TPS25921AD is an active electronic fuse (eFuse) with integrated hot-swap controller capabilities. It is designed for robust power protection in systems requiring a wide operating voltage range of 4.5V to 18V, with a maximum continuous voltage of 20V.

 

This eFuse features an adjustable current limit, configurable from 0.4A to 1.6A, with a typical on-resistance of 90mΩ. It provides essential protection mechanisms including overcurrent protection with current limiting response, overvoltage protection with cut-off response, and short-circuit protection. Thermal shutdown is also included to safeguard the device and system.

 

The TPS25921AD offers an auto-retry fault response, along with adjustable soft start and programmable dV/dt control for smoother power-up sequences. A fault output signal is available for indicating thermal shutdown, undervoltage lockout (UVLO), and overvoltage protection (OVP) events.

 

Packaged in an 8-SOIC format, this component is designed for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ), making it suitable for various environmental conditions.
