13. A system including an isolated gate driver comprising:
a controller configured to output gate information and drive strength information;
the isolated gate driver including a first voltage domain portion configured to receive the gate information and the drive strength information, an isolation channel, and a second voltage domain portion arranged across the isolation channel from the first voltage domain portion, the first voltage domain portion further configured to transmit a modulated signal including the gate information and the drive strength information from the first voltage domain portion to the second voltage domain portion across the isolation channel, the gate information including a logical value of a gate control signal, the drive strength information being communicated in multiple bits of a serial word represented by the modulated signal, the second voltage domain portion including a demodulator circuit configured to demodulate the modulated signal and further including a gate signal output circuit coupled to the demodulator circuit and configured to supply the gate control signal to an output of the isolated gate driver based on the gate information and the drive strength information; and
a device including a gate control input coupled to the output of the isolated gate driver to receive the gate control signal.
