US 2015/0029626 A1 · CONTROLLER AREA NETWORK NODE TRANSCEIVER

Abstract

An electronic device comprises a control module, a transceiving module, a first isolator, and a second isolator. The control module is configured to generate a control signal in response to a signal from an MCU. The transceiving module comprises a transceiving unit, which further comprises a first switch and a second switch. The electronic device further comprises a first isolator and a second isolator. The first isolator is external to the transceiving unit and is coupled between the first switch and a bus. Moreover, the first isolator is configured to isolate a first spike current coming from the bus. The second isolator is external to the transceiving unit and is coupled between a terminal of the second switch and the bus. Moreover, the second isolator is configured to direct a second spike current coming from the bus to the ground.
