The EV2639B-R-00A is the reference design board for the MP2639B, a highly integrated, flexible, switch-mode battery charge management system for single-cell Li-ion and Li-Polymer batteries used in a wide range of applications. The demo board shows two operating modes: charge mode and boost mode. When input power is present, the board charges a single-cell battery with a programmable charge current up to 5A. In the absence of an input source, the board switches to boost mode through the PB pin control to power the VH pin from the battery with a current up to 3A. The evaluation board provides 4 LEDs to indicate the voltage-based fuel gauge and distinguish charge mode from boost mode. To guarantee safe operation, the EV2639B-R-00A has input over-voltage protection, battery over-voltage protection, thermal shutdown, battery temperature monitoring, and a programmable timer to prevent prolonged charging of a dead battery.
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.
EV2639B-R-00A is an authentic electronic component manufactured by Monolithic Power Systems, categorized under Development Tools. 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 EV2639B-R-00A datasheet above.
Electronic component spot-market pricing for EV2639B-R-00A 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 EV2639B-R-00A 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.
