摘要：
A control circuit for controlling two N-channel FETs determines whether charging has ended by detecting that two P-channel FETs have been off for a prescribed amount of time, based on comparison results from two comparators and, if charging is decided to have ended, the two N-channel FETs are set to the off state for just a set amount of time.
