Overview
The PD69104B2ILQ-TR is a Power Sourcing Equipment (PSE) controller manufactured by Microchip Technology, designed for IEEE 802.3at PoE+ and UPoE applications. It integrates four independent power switch channels with a centralized management interface. The device operates within a VQFN-48 package and supports cut tape or reel packaging formats. This component facilitates the implementation of multi-port PoE infrastructure while ensuring compliance with industry standards for power delivery over Ethernet networks.
Feature Summary
- Integrates four independent power switch channels for simultaneous PoE port management
- Supports IEEE 802.3at PoE+ and UPoE standards for enhanced power delivery capabilities
- Features a centralized management interface for simplified system integration and control
Applications
- Multi-port PoE network switches
- Wireless access point power distribution systems
- IP camera surveillance infrastructure
Procurement Notes
Verify the manufacturer designation carefully, as this part number is associated with Microchip Technology rather than Microsemi Corporation. Confirm the specific suffix 'B2' against official datasheets to ensure correct revision compatibility. Check current lifecycle status, as similar models in this series may be discontinued or subject to replacement recommendations from the manufacturer.
Selection Notes
Select this component when designing systems requiring four-channel PoE+ or UPoE support with integrated switching. Ensure the design accommodates the VQFN-48 package constraints and thermal requirements. Verify that the host controller can interface correctly with the device's management protocol. Consider alternative parts if the specific 'B2' variant is unavailable or obsolete.
Part Context
This component belongs to the PD6910x family of PoE PSE controllers, which are widely used in enterprise networking equipment. The family provides scalable solutions for powering remote devices over standard Ethernet cabling. The PD69104 variant specifically addresses the need for four-port implementations in compact form factors.
Replacement Considerations
Microchip recommends the PD77714T4ILQ-0101-0000-TR as a substitute for related PD69104 variants. Verify functional equivalence and pinout compatibility before substitution.
