TPS2102DBVT

Overview

The TPS2102DBVT is a Texas Instruments power distribution switch featuring two inputs and one output. It operates within a voltage range of 2.7 V to 4 V. The device provides an output current capacity of 0.5 A with a typical on-resistance of 250 mΩ for the primary channel. Quiescent current is specified at 0.75 µA. It includes inrush current control, reverse current blocking, and under-voltage lockout functions. The component is housed in a SOT-23-5 package and supports surface-mount installation.

Feature Summary

• Dual-input single-output power multiplexing capability
• Integrated inrush current control mechanism
• Reverse current blocking protection
• Under-voltage lockout functionality

Applications

• Portable electronic devices requiring dual power source selection
• Battery-powered systems needing efficient power routing
• Embedded applications utilizing low-voltage power distribution

Procurement Notes

Verify the specific suffix DBVT corresponds to the SOT-23-5 package configuration. Confirm that the operating temperature range meets the -40°C to +70°C requirement for the intended environment. Ensure compatibility with the 2.7 V to 4 V supply voltage limits during system design validation.

Selection Notes

Select this component when a low-profile solution for dual-source power switching is required. Consider its low quiescent current for battery life optimization. Evaluate the 250 mΩ on-resistance against system power loss constraints. Verify that the input voltage specifications align with available power rails.
