TPS22944DCKR

Power Distribution Switches, Load Drivers Overview

The TPS22944DCKR is a single-channel load switch manufactured by Texas Instruments, designed for power distribution applications. It operates within an input voltage range of 1.62 V to 5.5 V and features a maximum on-resistance of 1.2 Ohms. The device supports a continuous output current of 20 mA with a fixed current limit of 100 mA. It utilizes an SC-70-5 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates high-side switching capability with built-in overcurrent protection mechanisms.
• Provides low on-state resistance to minimize power loss during conduction.
• Supports fast turn-on and turn-off transitions for efficient load management.

Power Distribution Switches, Load Drivers Applications

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific manufacturer part number against official Texas Instruments documentation to ensure compatibility with design requirements. Confirm that the SC-70-5 package dimensions and thermal characteristics align with the target PCB layout. Check for any recent product change notifications or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single-channel high-side switch with moderate current capacity is required. Ensure the 1.2 Ohm on-resistance meets the voltage drop constraints of the application. Verify that the 100 mA current limit provides adequate headroom for peak load currents without triggering unnecessary shutdowns during normal operation.

Power Distribution Switches, Load Drivers Part Context

This device belongs to the TPS2294x series of load switches from Texas Instruments. It shares architectural similarities with other members like the TPS22942 and TPS22943 but differs in specific electrical parameters such as current handling and on-resistance. The series is designed for space-constrained applications requiring reliable power management in small packages.
