Title:
VOLTAGE DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/059232
Kind Code:
A1
Abstract:
Provided is a voltage detection device which, in detection of voltage with regard to a plurality of resistive elements connected in parallel, makes it possible to decrease error and deviations in the detected voltage which occur due to the effects of the temperature and the configuration of pattern wiring. A voltage detection device 10 comprises: a resistive part 20 that has a plurality of resistive elements R1- R7 connected in parallel; a differential amplifier circuit 50; a first connection part 30 that has two wiring parts 31, 32 which connect differing positions of one end part 20A of the resistive part 20 with an input terminal 50A of the differential amplifier circuit 50; and a second connection part 40 that has two wiring parts 41, 42 which connect differing positions of the other end part 20B of the resistive part 20 with an input terminal 50B of the differential amplifier circuit 50. The voltage can be detected with regard to the resistive part 20 on the basis of the voltage of an output terminal 50C of the differential amplifier circuit 50.
