Claim Text:
1. A controller comprising: a high-side circuit referenced to an offset-voltage reference that is offset voltage-wise relative to a ground reference of the controller; a low-side circuit operable to output a control signal for the high-side circuit, wherein the control signal is referenced to the ground reference; a level-shift circuit 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; a data-validation circuit 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.
