Abstract
In some examples, this disclosure describes a method of controlling a high-side power switch and a low-side power switch arranged in a half bridge configuration. The method may comprise driving the gate of the high-side power switch based on high-side pulse modulation (PM) signals; driving a gate of the low-side power switch based on low-side PM signals; and monitoring the high-side PM signals and the low-side PM signals. The high-side PM signals and the low-side PM signals are configured to turn the high-side power switch and the low-side power switch ON and OFF in a complementary fashion, and monitoring may include: detecting one or more absences of either the high-side PM signals or the low-side PM signals; and generating a fault signal in response to detecting the one or more absences.
