One kind of transient triggering electrostatic discharge protection circuit

2014 
The present invention discloses a transient triggering electrostatic discharge protection circuit comprising transient trigger module, module clamp transistor is turned on, and the clamp transistor. The present invention provides one kind of transient triggering electrostatic discharge protection circuit, without using a current mirror, greatly reducing the area of ​​application of transient triggered ESD protection circuit, while the ratio of the current mirror, it is possible during an ESD event ends after a quick pull-down NMOS transistor corresponding gate potential down to 0, in order to reduce leakage; R Since the resistance of the PMOS transistor MR with the replacement, so that the RC time constant equivalent to the advent of smaller instantaneous ESD strike, and then becomes large, and therefore can be effectively prevented quickly brought the situation on the electricity false triggering.
