TPS25921LD Description

Short technical summary and product information.

The Texas Instruments TPS25912LD is an active electronic fuse (eFuse) with integrated hot-swap controller capabilities. It is designed to protect circuits from overcurrent and overvoltage conditions.

 

The device operates over a wide input voltage range of 4.5V to 18V, with a maximum continuous voltage of 20V. It offers precise current limiting, adjustable from 0.4A to 1.6A, with a typical accuracy of ±2% at 1A and 25°C. The eFuse features a low on-resistance of 90mΩ typical and a low quiescent current of 0.00041A typical.

 

Key protection features include overcurrent protection, overvoltage protection with a cut-off response, short-circuit protection, and thermal shutdown. It also includes an adjustable soft-start function and a fault output for signaling protection events. The device supports both auto-retry and latch-off fault responses.

 

Packaged in an 8-SOIC surface mount package, the TPS25921LD is suitable for various power management applications requiring robust protection and control. The operating temperature range is -40°C to 125°C junction temperature.
