Abstract
An electrostatic discharge (ESD) corner clamp is connected to a positive ESD rail that has a steady first voltage, such as 2.6V, and can be driven to a larger second voltage, such as 4.3V. The ESD corner clamp provides 5V tolerance by utilizing a keep off circuit that prevents the corner clamp from triggering when the voltage on the positive ESD rail changes from the first voltage to the second voltage.
