TPS2044BD Description

Short technical summary and product information.

The Texas Instruments TPS2044BD is a power distribution switch IC designed for robust power management in applications prone to heavy capacitive loads and short circuits. This device features four N-channel MOSFET power switches, each capable of handling 500mA continuous current with a typical on-resistance of 70mΩ.

 

The TPS2044BD operates over an input voltage range of 2.7V to 5.5V, making it suitable for a variety of systems. It incorporates essential protection features including fixed current limiting, over-temperature protection, and undervoltage lockout (UVLO) to safeguard both the load and the power source. The device also provides a status flag for fault reporting and features an active-low enable input.

 

Packaged in a 16-SOIC surface-mount configuration, the TPS2044BD is designed for efficient integration into printed circuit boards. Its operating temperature range is -40°C to 125°C (TJ), ensuring reliable performance in demanding environments. The low standby supply current of 1µA (typical for dual-channel configurations) minimizes power consumption when not active.
