Overview

The DP83826IRHBR is a low-power 10/100 Mbps Ethernet physical layer transceiver designed for industrial communications. It supports both MII and RMII interfaces and is optimized for low latency and deterministic performance in harsh environments.

Why Choose This Part

This PHY features extremely low power consumption, drawing only 45mA in 100Base-TX MII mode, and includes advanced power-down modes like Deep Power Down. It offers integrated terminal resistors and a small 5x5mm VQFN package to reduce overall BOM count and PCB area.

Applications

Industrial Automation
Ideal for programmable logic controllers (PLCs) and industrial gateways requiring reliable 10/100 Ethernet connectivity.
Motor Control Networking
Utilized in networked motor drives where low latency and small package footprints are critical for synchronized control.
Energy Efficient Systems
Suitable for battery-backed or thermal-constrained designs using IEEE 802.3az Energy Efficient Ethernet and Wake-on-LAN.
