Abstract (en)
[origin: WO2021173128A1] Embodiments of the invention include an under-voltage lockout (UVLO) circuit with automatic UVLO threshold configuration. In an embodiment, the UVLO circuit includes an over-voltage protection circuit that receives power from a power source, a peak detector that detects a peak voltage output for the external power source, a voltage threshold generator that sets a UVLO threshold based on the peak voltage output, and a comparator that compares an instantaneous voltage with the UVLO threshold and configures an operating mode of a device based on the comparison.
