Abstract
Described herein are systems and methods for real-time fault detection in electrical circuits. Various embodiments provide a fault detection circuit that uses a resistor network that is controlled to detect an internal current leak in multiple directions, e.g., to ground or to a power supply. The magnitude of the leakage current may be estimated from voltage measurements at voltage pins. In addition, as part of circuit diagnostics, open and short circuit fault conditions may be identified by using current sources and measuring deflections at the voltage pins.
