The MP2681B is a highly integrated Li-ion or Li-polymer switch-mode battery-charge controller with full protection and status indication. This part integrates a precision voltage reference and charge status indications suitable for AC adapter input and cradle charger applications. The MP2681B detects automatically the battery cell through a battery ID resistor and regulates the battery voltage according to the corresponding cell configurations: 3S, 4S, and 5S. Then, the AC adapter output is regulated automatically according to the chosen battery configuration. Additionally, if the battery pack does not have an ID resistor, the charge termination voltage can be configured by setting a dedicated voltage to the ID pin, according to the pre-set VID values representing the battery configuration. The MP2681B charges the battery in three phases: pre-charge, constant current and constant voltage. Charge is terminated when the current reaches a minimum set level. An internal charge timer provides safety back-up. The MP2681B provides a fixed pre-charge mode for deeply-discharged batteries and safety features that include battery temperature monitoring, NTC control, charge time-out, and fault control.
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.
EV2681B-S-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 EV2681B-S-00A datasheet above.
Electronic component spot-market pricing for EV2681B-S-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 EV2681B-S-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.
