TPS2051BDR Description

Short technical summary and product information.

The TPS2051BDR from Texas Instruments is a fixed current-limit power switch designed for robust power distribution. It incorporates a 70mΩ N-channel MOSFET, providing 500mA of continuous current.

 

The device operates within a voltage range of 2.7V to 5.5V and features accurate current limiting between 0.75A and 1.25A, with a typical accuracy of 0.25A at 1A. Protection mechanisms include current limiting, over-temperature shutdown, and undervoltage lockout (UVLO).

 

Designed for applications where short circuits are likely, the TPS2051BDR offers thermal and short-circuit protection. It has a typical rise time of 0.6ms and an active-high enable input. The switch type is general purpose, with an output configuration as high-side.

 

Packaged in an 8-SOIC (0.154", 3.90mm Width) surface-mount package, this component is suitable for various power management needs. The operating temperature range is -40°C to 125°C (TJ).
