Patent ID: 11936496
Assignee: MICROCHIP TECHNOLOGY INCORPORATED
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 2:
3. A controller area network (CAN) transmitter, comprising:
an output stage circuit including a CANH port and a CANL port;
an input stage circuit to receive an input signal, the input signal to indicate whether the output stage circuit is to provide dominant or recessive states;
a first cascode circuit to provide output signals on the output stage circuit to provide dominant or recessive states based on the input signal;
a first switch circuit to, based upon the input signal, switch the first cascode circuit on and off;
wherein:
the first switch circuit includes a resistor and a switch circuit transistor; and
based on the input signal, the resistor is to provide a voltage drop across a gate and a drain of the switch circuit transistor sufficient to turn on the switch circuit transistor.
