TPS2377PW

Overview

The TPS2377PW is a Powered Device 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 features a maximum on-resistance of 1 Ohm. The device supports a current limit of 405 mA and delivers an output power of 12.95 W. It functions reliably across a temperature range of -40°C to +85°C. The component utilizes a TSSOP-8 surface-mount package and maintains a low operating supply current of 240 uA.

Feature Summary

• Complies with IEEE 802.3af PoE Powered Device standards
• Integrates high-voltage power switch with low on-resistance
• Includes built-in thermal shutdown protection

Applications

• PoE-powered network endpoints
• Wireless access points
• IP security cameras

Procurement Notes

Verify the specific suffix 'PW' corresponds to the TSSOP-8 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the 0 V to 57 V input range and 405 mA current limit specifications for the target application environment.

Selection Notes

Select this component for standard 802.3af powered devices requiring a compact surface-mount solution. The TSSOP-8 package offers space efficiency compared to larger footprints. Consider the 240 uA quiescent current for power-sensitive designs. Evaluate thermal performance within the specified -40°C to +85°C operational window during system planning.

Part Context
