VOLTAGE SENSOR MODULE AND VOLTAGE MONITORING APPARATUS
First Claim
1. A voltage sensor module monitoring a voltage of each of a plurality of battery cells, comprising:
- a first terminal and a second terminal each to receive a voltage applied between both ends of the plurality of battery cells;
a third terminal and a fourth terminal each to receive a voltage applied between both ends of a battery cell to be monitored which is included in the plurality of battery cells;
a first reference voltage generation circuit connected to each of the first terminal and the second terminal and to generate a first reference voltage based on the voltage applied between the both ends of the plurality of battery cells; and
a first comparator circuit to compare a first regulated voltage generated based on a voltage applied between the third terminal and the fourth terminal, with the first reference voltage.

Abstract
Provided is a voltage sensor module monitoring a voltage of each of a plurality of battery cells, including: first and second terminals each receiving a voltage applied between both ends of the plurality of battery cells; third and fourth terminals each receiving a voltage applied between both ends of a battery cell to be monitored which is included in the plurality of battery cells; a first reference voltage generation circuit connected to each of the first and second terminals and generating a first reference voltage based on the voltage applied between the both ends of the plurality of battery cells; and a first comparator circuit comparing a first regulated voltage generated based on a voltage applied between the third and fourth terminals, with the first reference voltage. As a result, low voltage detection can be performed with accuracy even when an output of a battery cell decreases.
