Monolithic Power Systems (MPS) MP2702 1A Linear Chargers
Monolithic Power Systems (MPS) MP2702 1A Linear Chargers are compatible with 1- to 2-cell Li-ion, Li-polymer, and LiFePO4 batteries. The MPS MP2702 chargers are also compatible with 2-cell to 6-cell NiMH batteries, with a maximum voltage of 26V. The chargers automatically charge batteries through four phases: trickle charge, pre-charge, constant-current (CC) fast charge, and constant-voltage charge. Connect a resistor between the dedicated ISET pin and the ground to set the charge current. Additionally, use the USBM pin to set the input current limit (IIN_LIM) before configuring the charge current.
