TPS22944DCKR Description

Short technical summary and product information.

The Texas Instruments TPS22944DCKR is a load switch designed to protect systems and loads from high-current conditions. It operates over an input voltage range of 1.62 V to 5.5 V and features a P-channel MOSFET with a low ON resistance, typically 400 mΩ at 5.5 V.

This device includes essential protection features such as a minimum current limit of 40 mA or 100 mA, undervoltage lockout (UVLO), and thermal shutdown to prevent damage during over-current events. The switch is controlled by an ON/OFF input compatible with low-voltage signals. The TPS22944DCKR is housed in a compact SC-70-5 package, making it suitable for space-constrained applications.

Key electrical characteristics include a shutdown current of less than 1 µA and ESD protection tested to 4000 V (HBM) and 1000 V (CDM). The operating temperature range is -40°C to 85°C.
