TPS23753APW

Power Over Ethernet (PoE) Controllers Overview

The TPS23753APW is a Powered Device (PD) controller and power switch IC compliant with IEEE 802.3at standards, designed for isolated flyback converter topologies. It operates within an input voltage range of 0 V to 57 V, featuring a maximum on-resistance of 1.2 ohms and a current limit of 405 mA. The device supports classification currents between 10 mA and 23 mA and functions reliably across temperatures from -40 °C to +125 °C. Packaged in a 14-pin TSSOP, it integrates surge current limiting and UVLO for robust PoE applications.

Power Over Ethernet (PoE) Controllers Procurement Notes

Verify the specific suffix 'PW' confirms the 14-pin TSSOP package variant during procurement. Ensure compatibility with isolated flyback designs as specified by the manufacturer. Confirm RoHS compliance status through official documentation before integration into final assemblies.

Power Over Ethernet (PoE) Controllers Selection Notes

Select this component for designs requiring IEEE 802.3at compliance with isolated output architectures. The 1.2-ohm on-resistance suits moderate power levels up to approximately 7 watts. Consider the TSSOP-14 footprint for surface-mount assembly constraints and thermal management requirements.

Power Over Ethernet (PoE) Controllers Part Context

Part of the Texas Instruments TPS2375 series, which provides integrated solutions for Power over Ethernet powered devices. This series targets applications needing simplified bill-of-materials by combining PD control and power switching functions into a single monolithic IC.

Power Over Ethernet (PoE) Controllers Replacement Considerations

Check for TPS23753APWR as a reel-packaged alternative within the same family. Verify pinout and electrical specifications against datasheets before substituting other PoE controllers.
