TPS2043BDR Description

Short technical summary and product information.

The Texas Instruments TPS2043BDR is a 3-channel, N-channel MOSFET power distribution switch suitable for power systems requiring multiple switches in a single package. It operates within a voltage range of 2.7V to 5.5V and offers a continuous current capability of 500mA per channel.

 

Key electrical specifications include a typical on-resistance of 70mOhm and a fixed current limit ranging from 0.75A to 1.25A, along with over-temperature and undervoltage lockout (UVLO) fault protection. The device features an active-low enable input and a typical rise time of 0.6ms, minimizing current surges during switching. The maximum standby supply current is 2uA.

 

This power switch is housed in a 16-SOIC package and is designed for surface mounting. It operates across a wide temperature range of -40°C to 125°C (TJ), making it suitable for various environmental conditions. The TPS2043BDR is intended for applications where heavy capacitive loads and short circuits are likely to be encountered.
