TPS22992RXPR

Power Distribution Switches, Load Drivers Overview

The TPS22992RXPR is a single-channel load switch from Texas Instruments designed for high-density power distribution. It features an 8.7 mΩ typical on-resistance and supports up to 6 A continuous current within a 0.1 V to 5.5 V input voltage range. The device includes adjustable rise time control via an external capacitor to manage inrush currents. It operates with a bias voltage of 1.5 V to 5.5 V and offers low quiescent current of 10 µA. The component provides a Power Good (PG) signal and integrates thermal shutdown protection, housed in a compact WQFN package.

Power Distribution Switches, Load Drivers Feature Summary

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix RXPR against the manufacturer datasheet to confirm the tape-and-reel packaging configuration and pinout compatibility. Ensure the design supports the required 1.5 V minimum bias voltage for proper operation. Confirm that the application environment remains within the specified -40°C to +125°C temperature range to maintain performance integrity.

Power Distribution Switches, Load Drivers Selection Notes

Select this component for designs requiring high current capacity with minimal voltage drop. The adjustable rise time feature is critical for managing large capacitive loads without tripping upstream protection. Compare against variants like the TPS22992S if integrated short-circuit protection is necessary, as the standard RXPR variant relies on external circuitry or thermal limits for fault handling.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS22992 family of load switches, which are engineered for portable and industrial electronics. The series emphasizes power density through low on-resistance and small footprint packages. It serves as a key component for power distribution networks where controlled power-up sequences and efficient energy transfer are prioritized over simple switching functions.

Power Distribution Switches, Load Drivers Replacement Considerations

Direct substitutes include other TPS22992 variants such as TPS22992RXP or TPS22992SRXNR, provided the package and electrical characteristics match the design requirements. Verify pin-to-pin compatibility before substitution.
