MP2700 1-to-2-Cell 26V/1A Linear Chargers

Monolithic Power Systems (MPS) MP2700 1-to-2-Cell 26V/1A Linear Chargers are for 1-cell to 2-cell Li-ion, Li-polymer, and LiFePO4 batteries, as well as 2-cell to 6-cell NiMH batteries. The MP2700 components can sustain a voltage of up to 26V. The MP2700 measures the battery voltage (V_BATT) and automatically charges the battery in four phases: trickle charge, pre-charge, constant-current (CC) fast charge, and constant-voltage charge. When the battery is charged to full voltage, the charge current decreases slowly due to the internal battery resistance. The MP2700 automatically terminates the charging when the charge current drops below the termination current (I_TERM) threshold. After termination, the MP2700 can recharge the battery automatically once V_BATT drops below the recharge threshold.
