Overview
The PD70201ILQ-TR is a Powered Device (PD) controller from Microchip Technology, designed for IEEE 802.3at (PoE+) and 802.3af (PoE) applications. It operates within a supply voltage range of 0V to 57V and supports a maximum power output of 47.7 W. The device features a single channel and is housed in a 32-VFQFN package with dimensions of 5x5 mm. It functions as a front-end controller with PWM capabilities, supporting detection, classification, and power supply phases over four pairs of Cat5 cables. The component operates within a temperature range of -40°C to 85°C and has a supply current of 200µA.
Feature Summary
- Supports IEEE 802.3at Type 2 and 802.3af standards for Powered Device applications
- Enables detection, classification, and power supply phases across four cable pairs
- Integrates PWM-based front-end control for PoE/PoE+ interfaces
Applications
- Evaluation of PD applications using the PD70201EVB47F board
- Development of 25W isolated flyback converter systems
- Implementation of Type 2 Powered Device interfaces
Procurement Notes
Verify the specific suffix ILQ-TR against the manufacturer's datasheet to confirm package type and reel specifications. Ensure compatibility with IEEE 802.3at/at standards for your design. Check moisture sensitivity levels and storage conditions prior to assembly. Confirm RoHS compliance status through official documentation before procurement.
Selection Notes
Select this component for designs requiring support for four-pair PoE applications exceeding standard Type 2 current levels. Consider the 32-QFN package for surface mount integration. Evaluate the 47.7 W maximum power capability against system requirements. Verify operating temperature range suitability for the intended environment.
Part Context
This part belongs to the PD70101/PD70201 family of Ethernet Power Sourcing Equipment controllers. It serves as a Powered Device controller rather than a PSE switch. The device complements other Microchip LAN solutions by providing comprehensive PoE front-end management for high-power applications.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult Microchip Technology for alternative components within the same product family or updated revisions.
