TPS2055AD Description

Short technical summary and product information.

The Texas Instruments TPS2055AD is a current-limited power distribution switch featuring an 80-mΩ N-channel MOSFET high-side switch. It is designed for applications where heavy capacitive loads and short circuits are likely. This device provides independent thermal and short-circuit protection with an overcurrent logic output.

 

The TPS2055AD operates within a voltage range of 2.7V to 5.5V and offers a continuous current of 250mA per channel. It includes CMOS- and TTL-compatible enable inputs and features a typical rise time of 2.5ms. The switch incorporates undervoltage lockout (UVLO) and a maximum standby supply current of 10 μA for single and dual configurations.

 

Packaged in an 8-SOIC surface-mount package, the TPS2055AD is suitable for various power distribution systems. Its fault protection includes current limiting, over-temperature protection, and UVLO, making it a robust solution for demanding applications.
