TPS2120YFPR

Overview

The TPS2120YFPR is a power multiplexer IC from Texas Instruments designed for power distribution applications. It operates within an input voltage range of 2.8 V to 22 V and supports up to 3 A output current with a maximum on-resistance of 75 mOhms. The device features adjustable current limiting capabilities and is housed in a DSBGA-20 package. It functions reliably across an extended temperature range from -40°C to +125°C, making it suitable for robust industrial and consumer electronics environments requiring efficient power switching.

Feature Summary

• Integrates priority power multiplexing functionality for managing multiple power sources
• Provides adjustable current limiting protection to safeguard downstream loads
• Features low on-resistance for efficient power transfer and minimal voltage drop

Applications

• Portable electronic devices requiring seamless power source switching
• Industrial control systems needing reliable power distribution
• Consumer electronics utilizing battery backup or dual-input power architectures

Procurement Notes

Verify the specific suffix YFPR corresponds to the required tape-and-reel packaging configuration. Confirm that the DSBGA-20 footprint matches your PCB layout constraints. Ensure the operating voltage and current limits align with your system's power requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-channel power mux with high voltage tolerance is required. Compare against the TPS2121 if additional channels are needed. Verify thermal performance under maximum load conditions due to the small package size. Ensure compatibility with the system's control logic levels for the enable pins.

Part Context

This part belongs to the TPS2120 series of power switch ICs manufactured by Texas Instruments. The series focuses on providing integrated solutions for power path management and distribution in compact form factors. It complements other PMIC offerings by addressing specific needs for multi-source power selection in space-constrained designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as variants with different current ratings or packaging options. Verify functional equivalence regarding current limit thresholds and on-resistance values before substituting.
