Battery monitoring device and battery monitoring system

摘要

A battery monitoring system includes a clock input terminal, a data input terminal, a communication control circuit receiving the clock signal and the data signal from the clock input terminal and the data input terminal, respectively, a main power regulator controlled by the communication control circuit to supply and stop supplying main power, a charge circuit charged by the clock signal, and a sub power regulator started by a charge voltage of the charge circuit to supply a sub power to the communication control circuit. The communication control circuit controls the main power regulator with the data signal when the sub power is received from the sub power regulator.
