Abstract

See full text

An electronic device and a method for overcurrent detection are disclosed herein. The electronic device causes a high-side offsetting voltage drop and converts a voltage difference between a first voltage at an input terminal of an upper-bridge power component of a power stage and a sum of a first balancing voltage drop and the high-side offsetting voltage drop into a first current. The electronic device further converts a voltage difference between a second voltage of an output terminal of the upper-bridge power component and a second balancing voltage drop into a second current, compares the first current and the second current, and generates a high-side overcurrent protection (OCP) signal with logic high for a driver of the power stage when the first current is stronger than the second current, such that the driver turns off the upper-bridge power component accordingly.
