LTC9111 Datasheet Industrial Spoe Pd Controller

Manufacturer: Analog Devices

Overview: LTC9111 Industrial SPoE PD Controller.

General Description

The LTC®9111 is an IEEE 802.3cg compliant Single-Pair Power over Ethernet (SPoE) Powered Device (PD) controller.

A wide 2.3V to 60V operating range capability with polarity correction make the LTC9111 particularly well suited for classification-based systems in building and factory automation.

SCCP-based classification ensures full operating voltage is applied by the Power Sourcing Equipment (PSE) only when a valid PD is connected.

Key Features

  • n IEEE 802.3cg Compliant n Wide Input Voltage Range: 2.3V to 60V n Supports Serial Communication Classification Protocol (SCCP) n Wakeup Signature n Integrated 3.5V Standby Regulator n 150µA Maximum Current During Classification n Drives Low-Side Bridge MOSFETs for Polarity Correction n Charge Pump Enhances External N-Channel MOSFET n Pin Programmable Class Configuration n Available in 12-Pin MSOP and DFN 4mm × 3mm Packages.
