Methods, apparatus, and articles of manufacture to communicate multiple signals over an isolation channel

A system comprising:

• a processor integrated circuit (IC) having an output terminal and an input terminal;
• a gate driver IC having an isolation channel, a first output terminal on a first side of the isolation channel, a second output terminal on a second side of the isolation channel, and an input terminal on the first side of the isolation channel, the first output terminal of the gate driver IC coupled to the input terminal of the processor IC, the input terminal of the gate driver IC coupled to the output terminal of the processor IC;
• and
• a power switch having a control terminal coupled to the second output terminal of the gate driver IC, the gate driver IC to:
• at least one of (a) cause transmission of a control data signal for the power switch over the isolation channel or (b) provide a feedback data signal received from the second side of the isolation channel to the processor IC, the feedback data signal indicative of a status associated with the power switch;
• and
• cause transmission of a power signal for driving the power switch over the isolation channel.

An apparatus comprising:

• a first die having a first terminal;
• a second die having a second terminal;
• an isolation channel coupled between the first terminal of the first die and the second terminal of the second die;
• and
• control circuitry disposed on the first die, the control circuitry to:
• cause transmission of a control data signal over the isolation channel during a first portion of a communication period;
• detect a feedback data signal during a second portion of the communication period;
• and
• cause transmission of a power signal over the isolation channel during a third portion of the communication period.
