TPS2042BDGNR Description

Short technical summary and product information.

The Texas Instruments TPS2042BDGNR is a 2-channel, fixed current-limit power distribution switch. It is designed for applications where heavy capacitive loads and short circuits are likely to be encountered. Each switch is controlled by a logic enable input and features a 70mΩ N-channel MOSFET power switch.

 

Key electrical specifications include a continuous current rating of 500mA per channel and an operating voltage range of 2.7V to 5.5V. The device offers accurate current limiting, thermal and short-circuit protection, and undervoltage lockout (UVLO). It also includes a deglitched fault report for overcurrent conditions.

 

The TPS2042BDGNR is available in an 8-HVSSOP package and is designed for surface mount applications. The operating temperature range is -40°C to 125°C (TJ). The enable function is active-low, and the device has a typical rise time of 0.6ms.

 

This power switch is suitable for various power distribution systems requiring multiple power switches in a single package, minimizing current surges during power-up.
