MP26123DR-LF-Z 600kHz Switching Li-Ion Battery Charger|MPS代理

　　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.
