TPS2044ADG4 Description

Short technical summary and product information.

The Texas Instruments TPS2044ADG4 is a current-limited power distribution switch designed for applications with heavy capacitive loads and potential short circuits. It incorporates four N-channel MOSFET high-side switches, each controlled by an independent logic enable input.

 

Each channel provides 500mA of continuous current and features independent thermal and short-circuit protection with an overcurrent logic output. The device operates over a voltage range of 2.7V to 5.5V and has a typical rise time of 2.5ms. It includes undervoltage lockout (UVLO) and a status flag feature.

 

This power switch is housed in a 16-SOIC package and is designed for surface mounting. Its fault protection mechanisms include current limiting, over-temperature protection, and UVLO, making it suitable for robust power management solutions.

 

The TPS2044ADG4 is part of the TPS204xA family, known for their high-side MOSFET switch capabilities in a single package.
