CIRCUIT UNIT FOR DISCONNECTED SERIAL BUS LINE TERMINATION LOAD Russian patent published in 2019 - IPC G06F13/40 H04L25/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to circuit units for disconnected terminal load of a serial bus line. Technical result is achieved by the fact that circuit unit provides implementation of terminal load of line or terminal resistor of serial bus, for example CAN-bus, in disconnected form, with possibility of electronic connection or disconnection by means of electronically controlled switching elements and microcontroller, or preferably its computer port, available in electronic control unit of microcontroller. This provides preferable possibility of connection/disconnection of terminal resistor (matching resistor), for example, within programming of line end during manufacture of vehicle.

EFFECT: providing connection (installation) or disconnection (rejection) of required terminal resistors depending on actual configuration of serial bus or configuration of corresponding bus and control unit and providing functionality without negative effect on signal transmission.
