TPS2021DR Description

Short technical summary and product information.

The Texas Instruments TPS2021DR is a high-side N-channel MOSFET power switch designed for robust power distribution in applications prone to heavy capacitive loads and short circuits. It operates within a voltage range of 2.7V to 5.5V and provides a fixed current limit of 600mA, with a typical on-resistance of 33mΩ at a 5V input.

 

This device features an active-low, logic-level enable input and includes fault protection mechanisms such as current limiting, over-temperature protection, and undervoltage lockout (UVLO). The integrated charge pump controls rise and fall times to minimize switching surges. The TPS2021DR is available in an 8-pin SOIC package, suitable for surface mounting.

 

Key electrical characteristics include a typical rise time of 6.1ms and a maximum standby supply current of 10µA. It also provides 2kV Human-Body-Model and 200V Machine-Model ESD protection. The operating temperature range is -40°C to 125°C (TJ).
