Monolithic Power Systems (MPS) EV2658-Q-00A Charger Evaluation Board
Monolithic Power Systems (MPS) EV2658-Q-00A Charger Evaluation Board is designed to demonstrate the capabilities of the MP2658, a highly integrated switching charger intended for portable devices with different battery chemistries. The MP2658 supports up to 7-cell series Li-ion, Li-polymer, and LiFePO4 battery packs. It also supports lead-acid, super capacitor, NiMH, and NiCd battery packs from 2V to 31V. The device achieves up to 3A charge current with any battery regulation voltage (VBATT_REG).
The Monolithic Power Systems (MPS) MP2658 operates under a maximum 36VDC input voltage and hold-off voltage up to 45V. When an input power supply is present, the MP2658 generally charges the battery with four phases: trickle charge, pre-charge, constant-current charge, and constant-voltage charge.
