TPS259827LNRGER

The Texas Instruments TPS259827LNRGER is a versatile eFuse designed for robust power protection and hot-swap applications. It features a wide input voltage range from 2.7V to 24V and a low on-resistance of 2.7mΩ typical, enabling efficient operation.

This device offers a configurable current limit up to 15A with typical accuracy of ±8% for limits above 5A. It also provides an accurate current monitor output with ±1.5% typical accuracy at 25°C for currents above 3A. The eFuse includes adjustable fault management, circuit breaker, and current limiter options, along with adjustable over-current blanking timers to handle load transients without unnecessary tripping.

Packaged in a 24-VQFN (4x4) surface-mount package, the TPS259827LNRGER operates within a temperature range of -40°C to 125°C (TJ). Its design supports user-configurable fault responses, including latch-off or auto-retry with finite or indefinite retries and adjustable delay between retries, ensuring reliable system protection.

Key features include robust short-circuit protection and a fast-trip response time of less than 400ns typical. This makes the TPS259827LNRGER suitable for applications requiring reliable power sequencing and protection against overcurrent and short-circuit events.
