TPS23841PAPR

Overview

The TPS23841PAPR is a quad-channel Power Sourcing Equipment (PSE) controller compliant with IEEE 802.3af standards, designed for PoE applications. It integrates four independent power switches within a 64-pin HTQFP package. The device supports a supply voltage range of 21.5V to 57V and operates reliably across temperatures from -40°C to +125°C. Key electrical specifications include a maximum current limit of 650mA per channel and a maximum on-resistance of 1.8 ohms. It features internal switching capability and consumes approximately 10mA of supply current.

Feature Summary

• Complies with IEEE 802.3af PoE standards for power sourcing equipment
• Integrates four independent high-voltage power switches
• Supports wide input voltage range for flexible system design

Applications

• Quad-port Ethernet switch designs
• PoE midspan injectors

Procurement Notes

Verify the specific suffix 'PAPR' indicates tape-and-reel packaging when ordering. Confirm the manufacturer part number matches Texas Instruments documentation exactly. Ensure the component meets RoHS3 compliance requirements for your assembly process. Check moisture sensitivity level classifications prior to soldering.

Selection Notes

Select this component for systems requiring four isolated PoE ports under the 802.3af standard. Consider the 64-pin HTQFP package size for board layout constraints. Evaluate thermal performance given the operating temperature range and internal switch resistance. Verify that the 650mA current limit aligns with connected powered device requirements.

Part Context

This part belongs to the TPS2384 family of PoE controllers from Texas Instruments. It serves as a specialized integrated circuit for managing power delivery over Ethernet cables. The device simplifies design by combining control logic with power switching elements in a single package.

Replacement Considerations

The TPS23841PJD is a pin-compatible alternative offering similar functionality in a different package variant. Verify package dimensions and thermal characteristics before substitution.
