Patent ID: 8340163

Claim:
A dual watchdog communication circuit for implementing single line asynchronous dual watchdog communication for electrostatic discharge (ESD) noise immunity comprising: a source transceiver module; a sink transceiver module; said sink transceiver module being connected by a single line to said source transceiver module; said single line carrying communications between the source transceiver module and the sink transceiver module; each of said source transceiver module and said sink transceiver module using a coded pulse to implement the single line asynchronous dual watchdog communication for providing ESD noise immunity; and said source transceiver module including a transmitter, a first receiver coupled to the single line; a timer, a second receiver receiving an input to the source transceiver module; and a control block coupled to said transmitter, said timer, and said second receiver; said control block for controlling operation of said source transceiver module.
