Patent ID: 11962233
Assignee: SKYWORKS SOLUTIONS, INC.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 16:
17. An isolated gate driver comprising:
a first voltage domain portion including a transmit circuit;
a second voltage domain portion including a receive circuit; and
an isolation communication channel between the first and second voltage domain portions, the first voltage domain portion configured to receive gate information and additional information, the transmit circuit configured to transmit a serial word in multiple bit times from the first voltage domain portion to the second voltage domain portion across the isolation communication channel, by modulating a signal during each respective bit time of the multiple bit times to represent both the gate information and the addition al information, the gate information indicating a state of a gate control signal to control a device coupled to the second voltage domain portion of the isolated gate driver, the receive circuit including a demodulator circuit configured to demodulate the modulated signal transmitted across the isolation communication channel and a gate signal output circuit coupled to the demodulator circuit to supply the gate control signal based on the gate information, the gate information changing during transmission of the serial word, resulting in the gate control signal corresponding to an ON state of the device for at least one of the multiple bit times and an OFF state of the device for at least another of the multiple bit times.
