Hi Murali,

Can you describe the issue in more detail? From your explanation charging has stopped. It is possible you entered a fault condition. What do you observe on the STAT pin?

Hi Murali,

There are no issues when I am testing so this is not expected. Are you testing on the EVM? Take a waveform of REGN, SW, VBUS and charge current.
