  "textContent": "In an embodiment, a semiconductor device is disclosed that includes a buffer circuit that is configured to selectively output a charge signal to an inductor-capacitor node of a power driver to charge the inductor-capacitor node to a predetermined voltage level and an amplifier circuit that is configured to monitor a voltage differential across a capacitor of the inductor-capacitor node of the power driver. The amplifier circuit is configured to output a positive side signal and a negative side signal. The semiconductor device further includes an output that is configured to provide at least one signal based on the positive side signal and negative side signal to an analog-to-digital converter for measurement by a controller.",
