TPS2051D Description

Short technical summary and product information.

The Texas Instruments TPS2051D is a power distribution switch designed for applications with heavy capacitive loads and short circuits. This device is a high-side N-channel MOSFET power switch with a single output.

 

Key electrical specifications include an input voltage range of 2.7V to 5.5V, a continuous current rating of 500mA, and a typical on-resistance of 80mΩ at a 5V input. It offers fixed current limiting, over-temperature protection, and undervoltage lockout (UVLO) for fault protection. The switch is controlled via an active-high enable input.

 

The TPS2051D is available in an 8-pin SOIC package, suitable for surface mounting. The operating temperature range is -40°C to 125°C (TJ), with an ambient temperature range of -40°C to 85°C. It also includes ESD protection.

 

This power switch is intended for general-purpose applications where reliable power control and protection are required.
