Esd protection output driver

ESD is a major consideration in the design and manufacture of ICs. Texas Instruments always has been at the forefront of driving improvements in ESD protection and control, minimizing yield losses and field failures, and maintaining its reputation as a supplier of high quality, reliable products. What is ESD? An integrated circuit obtains improved protection of output buffers against damage from electrostatic discharge (ESD). Each output buffer is connected to its bondpad by means of a resistor, and protective clamping diodes are disposed around the periphery of the bondpad. It has been found that a suitably sized resistor allows the protective diodes to discharge an ESD Cited by:  · The primary protection consists of a dual diode ESD protection. The output driver perimeter can be kept at the minimum 80um. To ensure this small driver can shunt (a fraction) of the ESD current the foundry ESD rule (Silicide blocked, larger drain area) is used for the layout. The total silicon footprint is about um².

ESD protection circuits in advanced CMOS/SOI technologies. The devices are integrated in a flexible modular circuit design technique allowing for independent optimization of key characteristics. The IC application focus is on sensitive IOs, i.e. (ultra-)thin GOX input protection and robust output driver design using SCRs. RTSCR protection principle is explained in detail. When designing an ESD protection for output driver pins, one of two methods can be applied: (A) The output drivers are made self-protective to allow the main ESD current through the drivers or (B) parallel protection elements are added for shunting the main ESD current. A. Self-protective MOS. An integrated circuit obtains improved protection of output buffers against damage from electrostatic discharge (ESD). Each output buffer is connected to its bondpad by means of a resistor, and protective clamping diodes are disposed around the periphery of the bondpad.

The pull-down nMOS in the output buffer provides a path for the ESD pulse current to flow to ground, protecting the rest of the circuit from damage by the. An electrostatic discharge (ESD) protection circuit includes a diode that is 1, output driver includes a PMOS transistor P3 that is connected to. one differential line driver with three-state output and one guarantee a logic-high receiver output when the receiver ±15kV ESD Protection.
