ABSTRACT:
An Electrostatic Discharge (ESD) protection device extends the protection range of an ESD clamp circuit through hysteresis of the associated ESD clamp control circuit. Once the ESD clamp circuit is activated, an adjustment circuit applies a trigger level adjustment signal to the ESD clamp control circuit. The trigger level adjustment signal effectively increases the magnitude of the deactivation signal that is required to deactivate the ESD clamp circuit. Since the deactivation signal increases over time, a longer activation time of the ESD protection device is provided, which allows an extended protection range.
