TPS2113ADRBR

Overview

The TPS2113ADRBR is a source selector switch manufactured by Texas Instruments, designed for power path management in portable electronics. It features an N-channel internal FET and supports a 2:1 input-to-output ratio. The device operates within a supply voltage range of 2.8V to 5.5V and delivers a maximum output current of 1.25A. Quiescent current consumption is specified at 55 µA. The component exhibits a turn-on delay of 1 ms and a turn-off delay of 5 ms. It is housed in an 8-SON (3x3) package with exposed pad and functions reliably across a temperature range of -40°C to 85°C.

Feature Summary

• Integrates an N-channel MOSFET for efficient power path control
• Selects between two input sources to provide a single regulated output
• Provides low quiescent current operation suitable for battery-powered systems

Applications

• Handheld devices requiring dual-source power selection
• Mobile equipment needing redundant power input management
• Portable consumer electronics utilizing battery and USB charging paths

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the 8-SON package dimensions align with your PCB footprint requirements. Check RoHS compliance status and moisture sensitivity level ratings prior to assembly planning. Ensure the supplier provides valid traceability documentation matching the Texas Instruments part number.

Selection Notes

Choose this component when a compact solution is required for selecting between two power sources in mobile applications. The 1.25A current rating suits moderate load requirements. Consider the 55 µA quiescent current for extended battery life. Verify that the 2.8V minimum operating voltage matches your system's lowest expected rail voltage during discharge cycles.

Part Context

This part belongs to the TPS211xA series of OR controllers and source selector switches from Texas Instruments. It shares functional similarities with the TPS2115 but differs in maximum output current capabilities. The series is targeted at portable electronics where space constraints and power efficiency are critical design parameters.

Replacement Considerations

TPS2115ADRBR offers similar functionality with a higher 2A output current rating. Both parts share the same 8-SON package and pinout configuration. Verify if the increased current capacity of the alternative part meets or exceeds your application requirements.
