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

Claim 7:
8. 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 drive strength 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 drive strength 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 and with a drive strength based on the drive strength information.
