Power supply monitoring integrated circuit device for individually monitoring voltages of cells |
摘要 |
A power supply monitoring integrated circuit device for individually detecting the voltages of a plurality of lithium-ion cells connected in series has a plurality of comparators for comparing the voltages obtained by dividing the voltages of the individual cells with a predetermined voltage. The power supply monitoring integrated circuit device also has terminals for feeding electric power from the individual cells through resistors to the inputs of the individual comparators and terminals for supplying electric power from the individual cells to the individual comparators, and, in accordance with the results of comparison by the individual comparators, controls charging or discharging of the cells.
