TPS2052BDR Description

Short technical summary and product information.

The TPS2052BDR from Texas Instruments is a 2-channel, N-channel MOSFET power distribution switch suitable for power systems requiring multiple switches in a single package. It operates within a voltage range of 2.7V to 5.5V and provides a continuous current of 500mA per channel.

 

Key electrical characteristics include a typical on-resistance of 70mΩ and a fixed current limit ranging from 0.75A to 1.25A, with an accuracy of 0.25A at 1A. The device incorporates fault protection features such as over-temperature and undervoltage lockout (UVLO), along with a status flag output. The enable input is active high, controlling each switch independently.

 

Designed for robustness, the TPS2052BDR offers thermal and short-circuit protection. It has a typical rise time of 0.6ms, minimizing current surges during power-up. The maximum standby supply current is 1µA for dual-channel configurations. This power switch is available in an 8-SOIC surface mount package.

 

This component is intended for applications where heavy capacitive loads and short circuits are likely to be encountered, providing reliable power management and protection for downstream circuitry.
