POWER CLAMP CIRCUIT AND ELECTRONIC DEVICE INCLUDING POWER CLAMP CIRCUIT

This abstract first appeared for US patent application 20250098332 titled 'POWER CLAMP CIRCUIT AND ELECTRONIC DEVICE INCLUDING POWER CLAMP CIRCUIT

Original Abstract Submitted

a power clamp circuit includes an electro-static discharge (esd) current discharge circuit including a first mos transistor, a second mos transistor, and a third mos transistor that are coupled in series between a first power rail coupled to a supply voltage and a second power rail coupled to a ground voltage, a first triggering circuit including a first resistor, a first capacitor, and a fourth mos transistor and configured to trigger the first mos transistor, a second triggering circuit including a second resistor, a second capacitor, and a fifth mos transistor and configured to trigger the second mos transistor, and a third triggering circuit configured to turn off the third mos transistor during a normal operation and turn on the third mos transistor when an esd event occurs.
