Abstract: A controller includes a high-side circuit, a low-side circuit, a level-shift circuit, and a data-validation circuit. The high-side circuit is referenced to an offset-voltage reference that is offset voltage-wise relative to a ground reference of the controller. The low-side circuit is operable to output a control signal for the high-side circuit. The control signal is referenced to the ground reference. The level-shift circuit is configured to output a shifted signal to the high-side circuit that is referenced to the offset-voltage reference and based on the control signal. The data-validation circuit is configured to receive the shifted signal, determine a first value of the shifted signal at a first instant, determine a second value of the shifted signal at a second instant different in time from the first instant, and validate the shifted signal based on a determination that the first value and the second value correspond.
