Title:
ELECTRONIC CONTROLLER
Document Type and Number:
WIPO Patent Application WO/2023/003039
Kind Code:
A1
Abstract:
The electronic controller comprises: a first terminal (21) to which a control signal is input; a second terminal (22) connected to a low-potential side of a battery (30); a third terminal (23) connected to a high-potential side of the battery (30); an operating circuit (40) that performs a predetermined operation; a first resistor (61) connected to the first terminal (21); a second resistor (62) connected in series with the first resistor (61) between the first resistor (61) and the operating circuit (40); a surge absorption circuit (70) that is connected between the second terminal (22) and a first connection point (N1) between the first resistor (61) and the second resistor (62) and is configured to include Zener diodes (71, 72) to flow surge currents (I1, I2); and a Zener diode (80) in which a cathode is connected to a second connection point (N2) between the second resistor (62) and the operating circuit (40) and an anode is connected to the second terminal (22), wherein the surge absorption circuit (70) is configured to have a reverse withstand voltage equal to or higher than the battery voltage of the battery (30).
