TPS2042BDRG4 Description

Short technical summary and product information.

The TPS2042BDRG4 from Texas Instruments is a 2-channel, N-channel power distribution switch designed for applications with heavy capacitive loads and short circuits. 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 low on-resistance of 70mOhm (typical) and a typical rise time of 0.6ms. The device incorporates fault protection features such as current limiting, over-temperature protection, and undervoltage lockout (UVLO). It also includes a status flag for fault reporting.

 

This power switch is housed in an 8-pin SOIC package and is designed for surface mount applications. The device offers a maximum standby supply current of 1µA for single/dual configurations. Its operating temperature range is -40°C to 125°C (TJ).

 

The TPS2042BDRG4 is suitable for power-distribution systems requiring multiple power switches in a single package, offering controlled rise and fall times to minimize current surges during switching.
