ABSTRACT:
Provided are a charge and discharge control circuit capable of reducing a circuit size, and a battery device. In a charger reverse connection detection circuit (116), a comparison circuit or the like is not used, and two NMOS transistors are used, whereby circuit sizes of the reverse connection detection circuit (116) and a charge and discharge control circuit (110) are reduced. Accordingly, a consumption current is reduced, and a manufacturing cost is also reduced.
