Battery state monitoring circuit

摘要

In a battery state monitoring circuit and a battery device using the same, even if a charge inhibiting signal is inputted to a microcomputer control terminal, a lock mode is prevented from occurring in which both a charge control transistor and a discharge control transistor are turned OFF and a battery voltage can not be supplied to a load. A circuit is structured such that even if the charge inhibiting signal is inputted to the microcomputer control terminal, in the case where the overcurrent voltage detection terminal comes to have the overcurrent detection voltage, the charge inhibiting signal of the microcomputer control terminal is cancelled.
