Overview
The PD69101ILQ-13155TR is a single-port, mixed-signal, high-voltage Power over Ethernet (PoE) driver manufactured by Microchip Technology. It functions as an IEEE 802.3af/at compliant Powered Device (PD) controller and manager. The device supports operating supply voltages from 32 V to 57 V with current limits of 425 mA and 1.2 A. It features a maximum on-resistance of 300 mOhms and operates within a temperature range of -40°C to 85°C. Packaged in a 24-VFQFN exposed pad, it integrates classification and power management for Ethernet switch applications.
Feature Summary
- Integrates single-port PoE classification and power management logic
- Supports IEEE 802.3af and 802.3at standards
- High-voltage mixed-signal design for direct integration
Applications
- Ethernet switches
- Powered Device (PD) implementations
- Industrial networking equipment
Procurement Notes
Verify the specific suffix '13155' against official Microchip documentation to confirm tape-and-reel specifications and industrial temperature grading. Ensure compatibility with system voltage requirements between 32 V and 57 V. Confirm package integrity for the 24-VFQFN form factor prior to integration.
Selection Notes
Select this component for designs requiring integrated PoE PD control without external microcontroller dependency. The industrial temperature range (-40°C to 85°C) suits harsh environments. Verify that the 300 mOhm on-resistance meets efficiency targets for the specific power budget.
Part Context
This part belongs to the PD69101 family of PoE controllers. It serves as a complete solution for powering devices over Ethernet cables, combining analog front-end drivers with digital classification logic. The ILQ variant indicates the specific package and temperature rating configuration.
Replacement Considerations
Consult Microchip datasheets for direct pin-compatible alternatives within the PD6910x series. Verify electrical parameters such as current limit and on-resistance when substituting with other single-port PoE PD controllers.
