ESD224: Block diagram inquiry

Charles Zhang1

Part Number: ESD224

Hi Team,

The block diagram shows resistors between connector side and system side, what's the purpose of these resistors? And what's the impact of shorting C pin and S pin together?

Hi Charles,

The resistors are there to increase clamping performance of the device. If the C and S pins were shorted together, the device would not clamp properly during an ESD event, and possibly damage your system.

Hi Matt,

May I know this resistance between CS pins?

Hi Charles,

The DC resistance is about 3.6 Ohms.
