TPS23753APWR

Power Over Ethernet (PoE) Controllers Overview

The TPS23753APWR is a Power over Ethernet (PoE) Powered Device controller manufactured by Texas Instruments, designed for IEEE 802.3at compliance. It integrates classification, power switching, and DC/DC control functions within a single channel. The device operates with an input voltage range of 0 V to 57 V and supports a maximum current limit of 405 mA. It features a maximum on-resistance of 1.2 ohms and is housed in a TSSOP-14 package. The component is rated for operation between -40 °C and +125 °C, making it suitable for robust industrial and commercial networking applications requiring efficient PoE power delivery.

Power Over Ethernet (PoE) Controllers Feature Summary

• Integrates IEEE 802.3at classification logic for accurate power negotiation
• Combines high-voltage power switch with integrated DC/DC controller
• Supports isolated flyback converter topologies without optocouplers
• Provides precise current limiting and thermal protection mechanisms

Power Over Ethernet (PoE) Controllers Applications

• IP telephony systems
• Wireless access points
• Network surveillance cameras

Power Over Ethernet (PoE) Controllers Procurement Notes

Verify the specific suffix 'PWR' corresponds to the tape-and-reel packaging format when sourcing from distributors. Confirm that the manufacturer part number matches the exact revision level required for your design. Ensure compatibility with standard surface-mount assembly processes given the TSSOP-14 footprint. Cross-reference the RoHS status with current regulatory requirements for your target market before finalizing procurement orders.

Power Over Ethernet (PoE) Controllers Selection Notes

Choose this component for designs requiring a single-chip solution for 802.3at powered devices. It is ideal for applications needing low component count and simplified bill of materials. Consider its 405 mA current limit when sizing downstream loads. Evaluate the thermal performance within the TSSOP-14 package against your expected ambient operating temperatures.

Power Over Ethernet (PoE) Controllers Part Context

This part belongs to the Texas Instruments TPS2375x family of PoE controllers. It serves as a specialized integrated circuit for managing power delivery over Ethernet cables. The device simplifies the implementation of powered endpoints by combining classification and conversion control. It is distinct from non-PoE ethernet controllers and focuses solely on power reception and management.

Power Over Ethernet (PoE) Controllers Replacement Considerations

Check for direct pin-compatible alternatives within the same TI family if supply constraints exist. Verify that any substitute maintains identical 802.3at classification thresholds and current limit specifications. Ensure the replacement package matches the TSSOP-14 form factor for board layout compatibility.
