Abstract
An electronic system is disclosed, which includes a connector unit to communicate data with a host system, an electronic circuit to store the data, and a switch to convey the data to and from the electronic circuit via the connector unit. The switch includes a negative voltage protection unit coupled to the connector unit, and a transistor switch coupled to the negative voltage protection unit, the connector unit, and the electronic circuit. The negative voltage protection unit forces the transistor switch off if a negative voltage is detected.
