TPS2045AD Description

Short technical summary and product information.

The Texas Instruments TPS2045AD is a high-side N-channel MOSFET power distribution switch designed for applications requiring robust protection against capacitive loads and short circuits. It features independent thermal and short-circuit protection with an overcurrent logic output.

 

Key electrical characteristics include a continuous current rating of 250mA per channel and a low on-resistance of 80mOhm typical. The device operates over a wide voltage range of 2.7V to 5.5V and includes undervoltage lockout (UVLO) and over-temperature protection.

 

This switch is suitable for power distribution systems needing multiple power switches in a single package. Each switch is controlled by an independent logic enable input. The TPS2045AD is available in an 8-SOIC package and is designed for surface mounting.

 

It is intended for applications where heavy capacitive loads and short circuits are likely to be encountered, providing a safe operating level by limiting output current and shutting off the switch to prevent damage.
