TPS2550DBVR Description

Short technical summary and product information.

The Texas Instruments TPS2550DBVR is an adjustable, current-limited power distribution switch designed for various power management applications. It operates within an input voltage range of 2.5V to 6.5V and can handle a maximum current of 1.1A.

 

Key electrical characteristics include a typical on-resistance of 85mOhm and a current limit accuracy of 30% at 1A. The device features active-low enable, slew rate control, and robust fault protection including current limiting, over-temperature protection, and undervoltage lockout (UVLO). It also incorporates reverse input-output voltage protection, a built-in soft-start function, and a deglitched fault report.

 

Packaged in a compact SOT-23-6 surface-mount form factor, the TPS2550DBVR is suitable for space-constrained designs. The operating temperature range is -40°C to 85°C. This part is noted as not recommended for new designs, with an alternate product available.

 

This power switch is ideal for applications requiring controlled power delivery and protection against overcurrent conditions. Its features make it suitable for USB power switching, system power sequencing, and general-purpose power distribution.
