Abstract
A method and system for protecting low voltage devices driven by a high voltage circuit is disclosed. The method comprises monitoring an output voltage, from a high voltage block, to a low voltage block. The method further comprises comparing the output voltage with a range of voltages allowable for driving the low voltage block. The range of voltages may be pre-defined or dynamically determined. Furthermore, the method comprises operating a first set of switches and a second set of switches. The first set of switches are operated to feed voltage from the high voltage block to input of the low voltage block, and the second set of switches are operated to feed a plurality of reference voltages to the input of the low voltage block.
