About This Product

■Summary

The MP26124 is a monolithic DC/DC step-down switching charger for four series cell Li-ion battery packs. The MP26124 integrates a high-side power MOSFET capable of outputting up to 2A of charging current and also features peak current mode control for fast loop response and easy compensation. The MP26124 uses a sense resistor to control programmable charging current and two control loops to precisely adjust charging current and charging voltage. The MP26124 has multiple fault condition protection features, including cycle-by-cycle current limiting and thermal shutdown. Other safety features include battery temperature monitoring and protection, charging status display, and a programmable timer that stops the charging cycle when the timer expires. The MP26124 requires a minimal number of off-the-shelf external components and is offered in a QFN-16 (4mm x 4mm) package.
