TPS2375PW

Overview

The TPS2375PW is a Powered Device (PD) controller compliant with IEEE 802.3af standards, designed for Power over Ethernet applications. It operates within a supply voltage range of 0 V to 57 V and supports a maximum output power of 12.95 W. The device features an internal switch with a maximum on-resistance of 1 Ohm and includes current limiting set at 405 mA. It functions reliably across an extended temperature range from -40 °C to +85 °C. Packaged in an 8-pin TSSOP format, it draws a typical operating supply current of 240 µA.

Feature Summary

• Complies with IEEE 802.3af PoE standards for powered device control
• Integrates an internal high-side switch for direct load connection
• Supports wide input voltage operation suitable for PoE interfaces

Applications

• IEEE 802.3af Powered Device implementations
• Power management for LAN-connected equipment
• PoE interface circuit design

Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation to confirm exact electrical characteristics and package variations. Ensure compatibility with target IEEE 802.3af requirements before integration. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification records. Validate that the TSSOP-8 footprint matches the intended PCB layout constraints.

Selection Notes

Select this component for designs requiring strict adherence to IEEE 802.3af specifications with integrated switching capabilities. Consider the 1 Ohm on-resistance impact on thermal performance under full load conditions. Evaluate the 240 µA quiescent current contribution to overall system efficiency. Ensure the 8-TSSOP package dimensions fit within the available board space constraints.
