TPS2045ADR Description

Short technical summary and product information.

The TPS2045ADR from Texas Instruments is a high-side N-channel MOSFET power switch designed for power distribution systems. It operates within a voltage range of 2.7V to 5.5V and offers a continuous current capability of 250mA per channel.

 

Key features include a low on-resistance of 80mΩ typical, independent thermal and short-circuit protection with overcurrent logic output, and undervoltage lockout (UVLO). The switch is controlled by a CMOS- and TTL-compatible enable input and has a typical rise time of 2.5ms. The device also includes a maximum standby supply current of 10μA.

 

This power distribution switch is intended for applications where heavy capacitive loads and short circuits are likely to be encountered. It is housed in an 8-SOIC package and is designed for surface mounting.

 

Protection mechanisms include current limiting (fixed), over-temperature protection, and undervoltage lockout (UVLO), ensuring safe operation under fault conditions. The device also features ESD protection.
