TPS2551DBVR Description

Short technical summary and product information.

The Texas Instruments TPS2551DBVR is an adjustable, current-limited power distribution switch designed for various power management applications. This device features an N-channel output configuration and a high-side MOSFET with a typical Rds On of 85mOhm.

 

Key electrical characteristics include a maximum current rating of 1.1A and an adjustable current limit with an accuracy of 30% at 1A. The switch operates with an input voltage range of 2.5V to 6.5V and features an active-high enable signal. Fault protection mechanisms include current limiting, over-temperature protection, and undervoltage lockout (UVLO).

 

The TPS2551DBVR is supplied in a SOT-23-6 surface-mount package. It offers a fast overcurrent response time of typically 2 µs and a maximum standby supply current of 1 µA. The operating junction temperature range is -40°C to 125°C, with a package operating temperature range of -40°C to 150°C.

 

Note: This part is not recommended for new designs. Consider alternate products like the TPS2553.
