Abstract
An electronics (100, 200) including an electrical isolation is provided. The electronics (100, 200) include a bidirectional isolation circuit (110, 210) separating a first portion (100a, 200a) from a second portion (100, 200b) and a bus transceiver switch (120b, 220b) disposed in the second portion (100b, 200b). The bus transceiver switch (120b, 220b) is communicatively coupled to the bidirectional isolation circuit (110, 210). The bus transceiver switch (120b, 220b) receives from the bidirectional isolation circuit (110, 210) a communication control signal provided by the first portion (100a, 200a).
Claims20
An electronics including an electrical isolation, the electronics comprising:
- a bidirectional isolation circuit separating a first portion from a second portion;
- and
- a bus transceiver switch disposed in the second portion, the bus transceiver switch being communicatively coupled to the bidirectional isolation circuit for bidirectional signal transmission;
- wherein the bus transceiver switch receives from the bidirectional isolation circuit a communication control signal provided by the first portion to control the bus transceiver switch.
A method of electrically isolating a portion of an electronics, the method comprising:
- receiving with a bidirectional isolation circuit a communication control signal, wherein:
- the bidirectional isolation circuit separates a first portion and a second portion of the electronics;
- and
- the communication control signal is provided by the first portion;
- and
- providing with the bidirectional isolation circuit the received communication control signal to a bus transceiver switch disposed in the second portion to control the bus transceiver switch for bidirectional signal transmission.
