TPS22933ARSER

Overview

The TPS22933ARSER is a triple-input power multiplexer IC manufactured by Texas Instruments, designed for efficient power distribution in compact electronic systems. It features three independent inputs and two outputs, utilizing P-channel MOSFETs to manage power routing with low on-resistance of 3.3 ohms maximum. The device operates within a supply voltage range of 2.5 V to 12 V and supports an output current of up to 75 mA. Key timing parameters include a maximum turn-on time of 65 µs and a turn-off time of 32 µs. Packaged in an 8-UQFN (1.5x1.5 mm) surface-mount footprint, it functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrates three input sources into two selectable outputs for flexible power management
• Utilizes P-channel MOSFET technology for source selection switching
• Provides high isolation between active and inactive paths

Applications

• Handheld mobile devices requiring multiple power source selection
• Portable electronics needing redundant power input handling
• Battery-powered systems with dual-source charging or operation

Procurement Notes

Verify the specific suffix ARS against the manufacturer's official datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the ordering part number matches the required thermal performance and moisture sensitivity level. Cross-reference the component marking code with the latest production data sheet to avoid counterfeit risks during procurement.

Selection Notes

Select this component when designing circuits requiring three distinct power inputs routed to two loads. Consider the 3.3-ohm on-resistance impact on voltage drop at 75 mA loads. Evaluate the 65 µs turn-on delay against system startup requirements. Confirm that the 8-UQFN package fits the available PCB real estate and thermal dissipation constraints.

Part Context

This part belongs to the TPS22933 series of load switches and power multiplexers. It serves as a solution for managing power flow in portable applications where space efficiency and multi-source redundancy are critical. The UQFN package allows for dense board layouts typical in modern consumer electronics.

Replacement Considerations

Consult the manufacturer's cross-reference guide for direct pin-compatible alternatives. Verify electrical characteristics such as on-resistance and operating voltage ranges before substituting with other series components.
