TPS22921YZTR

Power Distribution Switches, Load Drivers Overview

The TPS22921YZTR is a single-channel high-side load switch manufactured by Texas Instruments. It operates within an input voltage range of 0.8 V to 3.6 V and supports a continuous output current of 2 A. The device features an ultra-low on-resistance (rON) of 14 mΩ, ensuring minimal power loss during conduction. It incorporates controlled turn-on capabilities to limit inrush current and includes integrated overcurrent protection with foldback functionality. The component is housed in a DSBGA-8 package measuring 1 mm x 1.5 mm, suitable for space-constrained designs.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'YZTR' corresponds to the tape-and-reel packaging format and the exact thermal/mechanical specifications required for your assembly process. Confirm that the component status aligns with your long-term production plans, as lifecycle changes may affect availability. Ensure compatibility with your PCB footprint dimensions for the DSBGA-8 package.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when low input voltage operation below 1.8 V is required alongside high current capability. The 14 mΩ rON makes it suitable for applications prioritizing efficiency over higher current ratings found in other family members. Consider the controlled turn-on feature if strict inrush current limits are mandated by the upstream power source or bus specification.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS2292x series of ultra-small, low-input-voltage load switches. It shares architectural similarities with the TPS22907 and TPS22920 but offers a distinct balance of 2 A current handling and 14 mΩ resistance. The series is designed for portable devices requiring efficient power routing in minimal board space.

Power Distribution Switches, Load Drivers Replacement Considerations

Direct substitutes include TPS22921YFPR and TPS22921YZPR, which share identical electrical characteristics. Alternative packages such as X2QFN may be considered if pinout compatibility allows. Verify that any replacement maintains the 14 mΩ rON and 2 A rating requirements.
