Hi,
In ESD testing for CC2541 and CC2541-Q1, we found a phenomena: During the ESD testing for the product with CC2541-Q1, the chip works well all the time. But the product with CC2541 will stop sending Bluetooth when the ESD voltage comes to 25kV. Waiting about 20mins, the Bluetooth signal recovers, i.e. can be scanned of the beacon. The ESD shots are applied on the plastic case of product.
Can anyone help to explain this problem? Why the industrial CC2541 need 20 minutes to recover? What's the difference between the ESD protection design of these two chips?
PS. the phenomenon is consistent.
