About This Product

■Summary

The MP26101 is a monolithic switching charger for 1-cell or 2-cell Li-ion battery packs. It has an integrated power MOSFET and can output up to 2A of charging current with current mode control, facilitating fast loop response and compensation. Charging current is programmable through a precise sense resistor. The MP26101 regulates charging current and charging voltage with two control loops, providing high accuracy for both constant current and constant voltage charging. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. Other safety features include a battery temperature monitor, charging status indicator, and a programmable timer to stop the charging cycle. The MP26101 requires a minimal number of readily available external components. The MP26101 is available in a 4mm x 4mm 16-pin QFN package.

■Features and benefits

・Charges 1-cell or 2-cell lithium-ion battery packs ・4.1V/cell full charging voltage ・3.9V/cell automatic recharge threshold ・Wide operating input range from 5V to 24V ・Programmable charging current up to 2A ・VBATT accuracy of ±0.75% ・0.2Ω internal power MOSFET ・Up to 90% efficiency ・Fixed 1.1MHz frequency - Preconditioning of fully depleted batteries ・Charging status indicator - Input power and battery failure indicators ・Thermal shutdown ・Cycle-by-cycle overcurrent protection ・Battery temperature monitoring and protection

■Available product numbers

・MP26101DR-LF-P MP26101DR-LF-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
