製品説明

The MP2612 is a monolithic switching charger for 2-, 3- series Li-Ion cells battery with a built in internal power MOSFET. It achieves up to 2A charge current with current mode control for fast loop response and easy compensation. The charge current can be programmed by sensing the current through an accurate sense resistor. MP2612 regulates the battery voltage and charge current using two control loops to realize high accuracy CC charge and CV charge. Fault condition protection includes cycle-­by­-cycle current limiting and thermal shutdown. Other safety features include battery temperature monitoring, charge status indication and programmable timer to finish the charging cycle. The MP2612 requires a minimum number of readily available standard external components. The MP2612 is available in 16-pin QFN package.

600kHz Switching Li-Ion Battery Charger

The MP26123 is a monolithic DC-DC step-down switching charger for 2- or 3-cell Li-ion battery packs. It has an integrated high-side power MOSFET can output up to a 2A charge current. It also has peak-current–mode control for fast loop response and easy compensation.  The MP26123 uses a sense resistor to control a programmable charge current, and accurately regulates the charge current and charge voltage using two control loops.  The MP26123 has multiple fault condition protections that include cycle-by-cycle current limiting and thermal shutdown. Other safety features include battery temperature monitoring and protection, charge status indication and programmable timer to cease the charging cycle when timer out.  The MP26123 requires a minimal number of readily-available external components.  The MP26123 is available in a 4mm x 4mm 16-pin QFN package.
