PM8801TR

Overview

The PM8801TR is a Powered Device (PD) interface and power switch IC from STMicroelectronics, compliant with the IEEE 802.3at standard for Power over Ethernet applications. It integrates a high-side power switch with a maximum on-resistance of 1 Ohm and a current limit of 640 mA. The device operates at a supply voltage of 48 V with a quiescent current of 900 uA. Designed for industrial environments, it functions within a temperature range of -40°C to +85°C and is housed in an HTSSOP-24 package.

Feature Summary

Integrates a high-side power switch with low on-resistance for efficient power delivery
Compliant with IEEE 802.3at standards for PoE powered devices
Includes integrated current limiting protection

Applications

Industrial Power over Ethernet systems
PoE LAN powered device interfaces
Power conversion circuits requiring 802.3at compliance

Procurement Notes

Verify component authenticity through authorized channels as the PM8801TR is listed as obsolete by the manufacturer. Confirm availability of stock or last-time buy options before finalizing procurement plans. Ensure that the HTSSOP-24 package specifications match the design requirements for surface mount installation.

Selection Notes

Select this component for designs requiring IEEE 802.3at PoE PD integration with a single-channel power switch. Consider the 1 Ohm on-resistance and 640 mA current limit when sizing thermal management solutions. The HTSSOP-24 package offers a compact footprint suitable for space-constrained industrial PCB layouts.

Part Context

The PM8801TR belongs to the PM8801 series of power switch ICs designed specifically for PoE and LAN applications. It serves as a dedicated interface solution for powered devices, combining control logic with power switching capabilities in a single integrated circuit form factor.
