Abstract
An electronic board includes a board, and includes on the board: a power input part inputting power output from an in-vehicle power supply; a drive circuit driving a drive source; a controller controlling driving of the drive source performed by the drive circuit; and a drive command signal input part inputting a drive command signal transmitted from outside. The electronic board further includes on the board: a drive command signal detection circuit capable of detecting the drive command signal, and controlling whether to supply the power input to the power input part to the controller based on whether the drive command signal is detected.
Claims6
An electronic board, comprising a board and comprising on the board:
- a power input part inputting power output from an in-vehicle power supply, wherein the power input part comprises a terminal;
- a drive circuit driving a drive source;
- a controller controlling driving of the drive source performed by the drive circuit;
- and
- a drive command signal input part inputting a drive command signal transmitted from outside, wherein the drive command signal input part comprises a terminal,
- wherein the electronic board comprises on the board:
- a drive command signal detection circuit capable of detecting the drive command signal input from the drive command signal input part, and controlling whether to supply the power input to the power input part to the controller based on whether the drive command signal input from the drive command signal input part is detected;
- and
- a choke coil that prevents a current flowing through the drive command signal detection circuit from becoming an overcurrent.
