BATTERY CHARGING DEVICE AND METHOD FOR CONTROLLING BATTERY CHARGING DEVICE

摘要

Provided is a battery charging device in which, when an input voltage becomes equal to or greater than a specified value, a control circuit for a battery voltage regulator circuit turns on a switch element if a charging permission signal is input or turns the switch element off if a charging stop signal is input. The control circuit turns off the switch element when the input voltage is less than the specified value. The control circuit forcibly turns off the switch element if a reverse connection detection signal is input when the input voltage is equal to or greater than the specified value and the charging permission signal is input.
