Overview
The TPS2375PWR-1 is a Power over Ethernet (PoE) Powered Device (PD) controller compliant with the IEEE 802.3af standard. It operates within an input voltage range of 0 V to 57 V and supports a maximum current limit of 405 mA. The device features a maximum on-resistance of 1 ohm and functions reliably across a temperature range of -40°C to +85°C. Packaged in a TSSOP-8 surface-mount format, it serves as a dedicated interface for PoE applications requiring Type 1 power classification.
Feature Summary
- Complies with IEEE 802.3af standards for Powered Device operation
- Supports wide operating input voltage ranges up to 57 V
- Integrated thermal protection mechanisms
Applications
- IEEE 802.3af Powered Device implementations
- Power-over-Ethernet LAN interface circuits
- Network equipment powered via Ethernet cabling
Procurement Notes
Verify the specific suffix 'PWR-1' against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with IEEE 802.3af requirements for your design. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and revision levels before procurement.
Selection Notes
Select this component for designs strictly adhering to the IEEE 802.3af Type 1 power budget. The 405 mA current limit defines the maximum load capacity. Consider the TSSOP-8 package constraints for PCB layout. Verify that the 1 ohm on-resistance meets the efficiency requirements of the target application compared to higher-power alternatives.
Part Context
This component belongs to the Texas Instruments TPS2375 series of PoE controllers. While other variants like the TPS23751 or TPS23752 support the higher-power IEEE 802.3at standard, the TPS2375PWR-1 is specifically configured for the lower-power 802.3af standard. It integrates the necessary control logic for PD detection and classification without the additional DC-DC controller features found in more complex integrated solutions.
Replacement Considerations
The TPS2375DR is a pin-compatible alternative in an SOIC-8 package. Both devices share identical electrical characteristics for IEEE 802.3af compliance.
