TPS2001CDGKR Description

Short technical summary and product information.

The TPS2001CDGKR from Texas Instruments is a power distribution switch designed for applications encountering heavy capacitive loads and short circuits, such as USB interfaces. It operates within an input voltage range of 4.5V to 5.5V and offers a rated current of 2A.

This device features a fixed, constant current limit with ±20% accuracy, ensuring a predictable fault current under various conditions. The on-resistance is specified at 72mΩ. It includes an active-high enable control, output discharge functionality, and reverse current blocking.

The TPS2001CDGKR provides a fast overcurrent response time of 2µs, which helps to ease the burden on the main 5V supply during output shorts. The power switch rise and fall times are controlled to minimize current surges during turn-on.

Available in SOT-23 and VSSOP packages, this power switch is suitable for surface mount applications. The operating temperature range is -40°C to 125°C.
