Abstract:
The present disclosure provides an SST driving circuit, a chip, and a driving output method. The SST driving circuit includes: a signal driver for driving and outputting a signal to be driven, the signal driver including termination resistors; a first electrostatic current discharge module, providing first discharge paths for electrostatic currents generated in the signal driver; a second electrostatic current discharge module, connected in series with the termination resistors, providing second discharge paths for the electrostatic currents; and a power clamp, used for conducting the power clamp circuit, the first discharge paths and the second discharge paths when a power supply voltage of the signal driver exceeds a clamping voltage. The present disclosure provides different discharge paths, which effectively reduces voltage borne by a protected device through a voltage division method, and improves the device's ability to protect against electrostatic discharge.
