TPS2104DBVR

Overview

The TPS2104DBVR is a dual-input, single-output power multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 500 mA. The device features a maximum on-resistance of 2.4 Ohms, with a maximum turn-on time of 340 µs and a maximum turn-off time of 6 µs. It functions reliably across an operating temperature range from -40°C to +85°C. The component is housed in a compact SOT-23-5 surface-mount package.

Feature Summary

• Provides seamless switching between two input sources to a single output load
• Integrates high-side N-channel MOSFET switches for low conduction loss
• Supports hot-swapping operations with controlled turn-on and turn-off timing

Applications

• Battery backup systems requiring automatic source selection
• Portable electronics needing redundant power path management
• Embedded systems utilizing multiple power inputs for reliability

Procurement Notes

Verify the specific ordering suffix to ensure the correct tape and reel quantity matches production requirements. Confirm that the SOT-23-5 footprint aligns with the target PCB layout. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the voltage rating covers the maximum expected input conditions without exceeding limits.

Selection Notes

Select this component when a dual-input power routing solution is required for low-voltage applications. Consider the 500 mA current limit to ensure it meets the load demands. Evaluate the 2.4 Ohm on-resistance against acceptable power dissipation levels. Verify that the 2.7 V minimum operating voltage is compatible with the system's power rails.

Part Context

This part belongs to the TPS210x series of power multiplexers designed for efficient power distribution. It serves as a critical interface for managing power sources in space-constrained designs. The SOT-23-5 package allows for minimal board area usage while maintaining robust electrical performance for portable devices.

Replacement Considerations
