TPS2042BDGNRG4 Description

Short technical summary and product information.

The TPS2042BDGNRG4 from Texas Instruments is a power distribution switch IC featuring two N-channel MOSFETs. It is designed to handle applications where high capacitive loads and potential short circuits are common. Each switch is controlled by a logic enable input and provides a fixed current limit for protection.

 

Key electrical specifications include an input voltage range of 2.7V to 5.5V, a continuous output current of 500mA per channel, and a typical on-resistance of 70mOhm. The device incorporates accurate current limiting, with a minimum of 0.75A and a maximum of 1.25A, along with over-temperature and undervoltage lockout (UVLO) fault protection. A deglitched fault report is provided for overcurrent conditions.

 

This load switch operates within an ambient temperature range of -40°C to 85°C and a junction temperature range of -40°C to 125°C. It is available in an 8-HVSSOP package and is suitable for surface mount applications. The device also features a typical rise time of 0.6ms and a low standby supply current of 1µA for dual-channel configurations.

 

The TPS2042BDGNRG4 is intended for power distribution systems requiring multiple power switches in a single package, offering thermal and short-circuit protection to safeguard connected loads.
