TPS2044DR Description

Short technical summary and product information.

The Texas Instruments TPS2044DR is a quad power-distribution switch IC designed for robust power management in systems prone to heavy capacitive loads and short circuits. Each of the four integrated N-channel MOSFET switches can handle 500mA of continuous current per channel.

 

This device operates within a supply voltage range of 2.7V to 5.5V. It features a maximum on-resistance of 135 mOhm (at 5V input) and includes essential fault protection mechanisms such as fixed current limiting, over-temperature shutdown, and undervoltage lockout (UVLO). The switch rise time is typically 2.5ms, minimizing current surges during activation.

 

The TPS2044DR is housed in a 16-pin SOIC package, suitable for surface mounting. It includes a logic-level enable input for control and provides an overcurrent logic output flag. The operating temperature range is -40°C to 85°C, making it suitable for a variety of environmental conditions.
