摘要:
An area-efficient, high voltage, dual polarity ESD protection device (200) is provided for protecting multiple pins (30, 40) against ESD events by using a plurality of stacked NPN devices (38, 48, 39) which have separately controllable breakdown voltages and which share one or common NPN devices (39), thereby reducing the footprint of the high voltage ESD protection circuits without reducing robustness and functionality.
