Abstract
An electronic device can be used with a system, such as an ignition system, that operates a relatively high voltage. The device can include a signal clamping control module that can include a signal reference module and a feedback control module. The signal reference module is operable to provide a reference signal to the feedback control module. The feedback control can be configured to receive a scaled signal from a signal scaling module, wherein the scaled signal is representative of a signal at a current carrying electrode of a power transistor. Based on the comparison of the reference signal to the scaled signal, the measurement module provides one or more signals to a control signal drive module. The feedback control module provides a control electrode signal to a control electrode of the power transistor.
