TPS25921ADR TI eFuse Power Switch | 8-SOIC | 5.5V, 5A, 28mΩ

Product Overview

The TPS25921ADR from Texas Instruments is a compact, feature-rich eFuse power switch designed for robust circuit protection in space-constrained applications. It integrates a low on-resistance (28mΩ) N-channel MOSFET to support continuous currents up to 5A with an input voltage range of 2.7V to 5.5V. The device provides programmable overcurrent protection, output slew rate control, and thermal shutdown, making it ideal for hot-swap and short-circuit protection in various electronic systems.

Detailed Technical Specifications

Key Features

• Low 28mΩ on-resistance minimizes power loss and heat dissipation.
• Programmable current limit from 0.5A to 5A using a single external resistor.
• Adjustable output slew rate for controlled inrush current.
• Reverse current blocking prevents back-feed during fault conditions.
• Thermal shutdown with hysteresis for reliable protection.
• Enable pin for ON/OFF control with active low logic.
• Under-voltage lockout (UVLO) for proper startup.
• Small 8-SOIC package suitable for space-limited designs.

Target Applications

The TPS25921ADR is ideal for a wide range of applications requiring reliable power path protection. Specific examples include:
