Overview
The MP8001DS-LF-Z is a Powered Device (PD) controller compliant with the IEEE 802.3af standard for Power over Ethernet applications. It operates at a maximum working supply voltage of 48 V and supports an output power capacity of 15 W. The device features a current limit of 420 mA and a maximum on-resistance of 1.2 Ohms. It functions within a temperature range of -40°C to +85°C and consumes a typical operating supply current of 240 uA. The component is housed in an SOIC-8 surface-mount package.
Feature Summary
- Complies with IEEE 802.3af standards for Powered Device classification
- Integrates power switching capabilities with detection logic
- Supports operation at standard 48 V PoE supply voltages
Applications
- IEEE 802.3af Powered Device integration
- Power over Ethernet LAN interface circuits
- Network endpoint power management
Procurement Notes
Verify the specific suffix, such as LF-Z, against official datasheets to confirm lead-free status and packaging type. Confirm RoHS compliance details directly from manufacturer documentation. Ensure the SOIC-8 package dimensions match your PCB footprint requirements before finalizing procurement decisions.
Selection Notes
Select this component for designs requiring strict adherence to the IEEE 802.3af PD specification. Evaluate the 1.2 Ohm on-resistance and 420 mA current limit against your load requirements. Consider the 240 uA quiescent current for low-power system efficiency targets.
Part Context
This part belongs to the MP8001 series of power switch ICs designed specifically for PoE/LAN applications by Monolithic Power Systems. It serves as a dedicated controller for managing power delivery in networked devices, distinguishing itself from general-purpose switches through its protocol-specific detection and classification features.
Replacement Considerations
Consult official MPS documentation for verified alternative part numbers within the same family or compatible generations. Do not assume functional equivalence with other PoE controllers without cross-referencing pinouts and electrical specifications.
