Abstract
A control system () and method () are provided where a first voltage domain circuit () and a power switch () operate in a first voltage domain and where a second voltage domain circuit () operates in a second voltage domain, where the second voltage domain circuit includes a gate driver circuit () for providing a control terminal driving signal (PWM) to drive the power switch, and also includes a watchdog communication circuit () for scheduling watchdog communications between the first and second voltage domain circuits to be temporally separated from noise-inducing signal transitions in the control terminal driving signal.
