TPS2042BDR Description

Short technical summary and product information.

The TPS2042BDR from Texas Instruments is a 2-channel, current-limited power distribution switch. It is designed to handle applications where high capacitive loads and potential short circuits are common.

 

Key electrical specifications include a continuous current rating of 500mA per channel and a low on-resistance of 70mOhm typical. The device operates over a wide input voltage range of 2.7V to 5.5V. It incorporates features such as thermal and short-circuit protection, undervoltage lockout (UVLO), and a deglitched fault report.

 

The TPS2042BDR utilizes N-channel MOSFETs and is controlled by a logic enable input. The internal charge pump manages gate drive to control power-switch rise and fall times, minimizing current surges during power-up. The device is available in an 8-SOIC package, suitable for surface mounting.

 

This power switch is ideal for USB power applications and other power distribution systems requiring multiple protected switches in a single package. Its accurate current limit and robust protection features make it a reliable choice for safeguarding downstream components.
