Abstract
Disclosed herein is a system including a power transistor having a first conduction terminal coupled to a supply node, a second conduction terminal coupled to an output node, and a control terminal controlled by a drive signal. The system further includes a driver configured to receive an input voltage from an external component and generate the drive signal based thereupon, and a sense circuit. The sense circuit is configured to, when the power transistor is powering a load coupled to the output node: detect whether the power transistor has entered an overload condition, and if so, determine a duration of time that the power transistor is in the overload condition; and assert a diagnostic signal in response to the duration of time being outside of a time window.
