Hi

1. May I know the ADC sampling rate of CCG3PA ?

2. For the current which is over OCP threshold for 1us time, could that be captured by LSCSA of CCG3PA?

Hi Grace,

1. CCG3PA internal ADC main frequency is 1MHz (Max value), the CCG3PA firmware use divider value with 8 for ADC sample. It is about 125KHz.

2. There is OCP denounce time setting in configuration table, 10ms by default. If you could like to capture it, you could set it as 0 to try. Please kindly notice that the OCP event is compactor interrupt triggered.

Best Regards,

Lisa
