MP8001DS-LF-Z

Overview

The MP8001DS-LF-Z is a Powered Device (PD) controller compliant with the IEEE 802.3af standard for Power over Ethernet applications. It integrates a detection and classification interface to verify power source compatibility before enabling power delivery. The device features an integrated 100V rated DMOS switch with a maximum on-resistance of 1.2 Ohms and a current limit of 420 mA. It operates within a supply voltage range up to 48 V, drawing a typical quiescent current of 240 uA. The component supports a maximum output power of 15 W and functions reliably across an operating temperature range from -40 C to +85 C in an SOIC-8 package.

Feature Summary

• Complies with IEEE 802.3af specifications for PoE powered devices
• Integrates a 100V rated DMOS switch with thermal protection
• Includes surge current limiting to prevent input capacitor overheating
• Provides open-drain power good output indication

Applications

• IEEE 802.3af compliant network endpoint devices
• Power over Ethernet powered equipment integration
• LAN interface power management circuits

Procurement Notes

Verify the specific suffix 'Z' indicates lead-free compliance and RoHS status against the manufacturer's official documentation. Confirm the SOIC-8 package dimensions and moisture sensitivity level requirements for surface mount assembly processes. Ensure the selected variant matches the required 420 mA current limit specification for the target application design.

Selection Notes

Select this component when designing systems requiring strict adherence to the IEEE 802.3af standard for power sourcing equipment interaction. The integrated DMOS switch simplifies bill of materials by eliminating external high-voltage switching components. Consider the 420 mA current limit and 1.2 Ohm on-resistance when calculating thermal performance and efficiency constraints for the powered device load.

Part Context

The MP8001 belongs to the MP8001 series of PoE PD controllers manufactured by Monolithic Power Systems. This family provides standardized interfaces for detecting and classifying power sources in Ethernet networks. The DS suffix typically denotes the SOIC-8 surface mount package option within the product lineup, distinguishing it from other packaging variants available in the same functional series.
