BATTERY VOLTAGE MANAGEMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a battery voltage management device reducing a power consumption and simplifying a circuit.

SOLUTION: This battery voltage management device includes a battery circuit A, and a read signal input circuit B and a read signal output circuit C that are interposed with photo MOS relays PH1 and PH2 respectively; and manages a battery voltage based on a signal output from the read signal output circuit C according to a signal output when the battery voltage is higher and lower than the set voltage of an IC1. Consequently, this device can reduce the power consumption and simplify the circuit.
