Miller clamp protection circuit, driving circuit, driving chip and intelligent IGBT module

A Miller clamp protection circuit being connected to a device to be driven, and comprising:

• a main driving circuit configured to provide a driving signal and output an intermediate signal, wherein an input voltage provided by a power supply is transferred to the intermediate signal;
• a Miller switch configured to reduce a voltage glitch;
• a Miller switch control circuit receiving the intermediate signal from the main driving circuit and configured to automatically control a on and off of the Miller switch according to the intermediate signal from the main driving circuit;
• the main driving circuit is connected to the power supply, the Miller switch control circuit, one end of the Miller switch and the device to be driven, and another end of the Miller switch is grounded;
• wherein when the device to be driven is turned on, the Miller switch control circuit controls the Miller switch to turn off according to the intermediate signal;
• when the device to be driven is turned off, the Miller switch control circuit controls the Miller switch to turn on according to the intermediate signal to discharge the voltage glitch.
