Monolithic Power Systems (MPS) MP2710 Li-ion/Li-Polymer Battery Chargers
Monolithic Power Systems (MPS) MP2710 Li-ion/Li-Polymer Battery Chargers feature system power-path management (PPM), ideal for space-constrained portable applications. The Monolithic Power Systems (MPS) MP2710 draws input power from either an AC adapter or USB port, allowing simultaneous battery charging and system operation. The charger supports pre-charge, constant current (CC), and constant voltage (CV) regulation, with features like charge termination and auto-recharge. The PPM function ensures uninterrupted system power by automatically selecting input power, battery power, or both.
