Overcurrent detector for a multi-channel level shifter module

An overcurrent detector for a multi-channel level shifter module that includes multiple level shifter circuits, the overcurrent detector comprising:

• an overcurrent detecting circuit including:
• a plurality of current sensing units, each of which is coupled to a respective one of the level shifter circuits to sense a current acquired through the respective one of the level shifter circuits, and is configured to output a sensed signal based on the current sensed thereby;
• and
• a plurality of overcurrent determination units, each of which is coupled to a respective one of said current sensing units for receiving the sensed signal therefrom, and has an output terminal to output a first indication signal when the sensed signal received by the overcurrent determination unit indicates that the current sensed by the respective one of the current sensing units is greater than a predefined current level, wherein said output terminals of said overcurrent determination units are coupled to each other at a common node, and said overcurrent detecting circuit is configured to output a second indication signal that indicates occurrence of overcurrent in one of the level shifter circuits when any one of said output terminals of said overcurrent determination units outputs the first indication signal.
