Methods and devices of the invention include an electrostatic discharge
(ESD) protection circuit. This circuit includes rise time dependent
activation circuitry capable of detecting a slew rate of an input signal
and capable of determining whether the slew rate of the input signal is
greater than a threshold value. For an ESD event said activation
circuitry generates a trigger signal. Additionally, the activation
circuitry is coupled with the ESD dissipation duration control circuitry
which is further coupled with an ESD dissipation circuit. This
arrangement enabling the duration control circuit to be activated by the
trigger signal which responds by producing an activation signal that
activates the ESD dissipation circuitry and that controls the length of
time the dissipation circuit remains active. The ESD dissipation
circuitry includes a shunt that redirects the ESD energy away from the
protected internal circuit. The ESD dissipation duration circuitry
further configured to maintain shunting of the energy for a period of
time sufficient to discharge of the ESD energy without damaging the
protected circuitry.
