The MP8021 is an IEEE 802.3af/at/bt compliant Power over Ethernet (PoE) powered device (PD). The device supports all the functions of IEEE 802.3af/at/bt, including detection, 5-event classification, inrush current (IINRUSH) control, and an external hot-swap MOSFET driver. During the start-up period, The MP8021 limits the hot-swap current below the inrush current limit. The device fully turns it on after the inrush period finishes. The MP8021 features an intelligent maintain power signature (MPS) function and input under-voltage lockout (UVLO) with a wide hysteresis. The integrated I2C interface can read back the mark event number and monitor the real-time power. The MP8021 can also set the power priority between dual-port PoE supplies or between the PoE and a DC auxiliary supply for seamless fail-over backup applications. The MP8021 is available in a TQFN-20 (5mmx5mm) package.
YG GROUP (YUGUANG INTERNATIONAL(HK)CO.,LTD) supports reliable sourcing through quality controls and compliance documentation. Please confirm product requirements, applicable certifications and supporting documents before ordering.
MP8021GUT-P is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Power Management ICs. It is supplied in the standard manufacturer-specified package footprint, providing industry-standard mechanical dimensions and terminal configurations for board-level assembly. Full pinout configurations, physical footprint drawings, and rated operating tolerances are documented in the official MP8021GUT-P datasheet above.
Electronic component spot-market pricing for MP8021GUT-P fluctuates based on real-time global availability, production date codes, minimum order quantities (MOQ), and packaging formats (e.g., Reel, Tube, Tray). Using an RFQ ensures you receive accurate, real-time volume pricing tied to verified, traceable inventory rather than stale catalog estimates.
Lead times for MP8021GUT-P depend on whether stock is dispatched from our central hub or regional franchise partners. Ready-to-ship inventory typically leaves the warehouse within 1–3 business days following quality inspection, while factory-direct or back-ordered allocations are confirmed with an estimated ship date upon RFQ reply.
