ABSTRACT:
A protection circuit protects an integrated circuit (“IC”) from peak voltages and includes a voltage divider coupled to a silicon controlled rectifier. The voltage divider allows for adjustment of the trigger voltage, trigger current, and holding voltage of the protection circuit so that the protection circuit can conduct current after a particular voltage level has been applied to the protection circuit without accidental triggering on by, for example, noise.
