The MP6543 family of products are all three-phase brushless DC motor drivers. They integrate three half-bridges, consisting of six N-channel power MOSFETs, along with pre-drivers, gate drive power supplies, and current-sense amplifiers. The MP6543 has ENABLE and PWM inputs for each ½-H-bridge. The MP6543A has separate high-side and low-side inputs, while the MP6543B has Hall-element inputs. Otherwise, they are similar. References to the MP6543 in this document apply to the other parts, unless otherwise noted. The MP6543 is able to deliver up 2A continuously (depending on thermal and PCB conditions), with the adjustable over-current protection threshold. It uses an internal charge pump to generate the gate drive supply voltage for the high-side MOSFETs, and a trickle-charge circuit to maintain sufficient gate drive voltage to operate at 100% duty cycle. Internal safety features include thermal shutdown, under-voltage lockout (UVLO), and over-current protection (OCP). The MP6543, MP6543A, and MP6543B are available in a 24-pin, 3mmx4mm QFN package with an exposed thermal pad.

MP6543BGL is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Driver 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 MP6543BGL datasheet above.
Electronic component spot-market pricing for MP6543BGL 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 MP6543BGL 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.
