ABSTRACT:
A protection circuit (40) providing positive and negative stress protection. A lateral PIN (58) assists in the triggering of a silicon-controlled rectifier (60) for positive stress protection. A vertical PNP (62) provides negative stress protection. A Schottky diode 64 may be used for biasing a n-well (44) to prevent latchup.
