BQ24230: DPPM issue when run out of battery

Hi Ting,

Can you show the waveforms for BAT (current and voltage) and OUT (voltage) when you plug the voltage in? This would help verify that the device is in DPPM mode. 

Hi Anthony:

      I provide BAT (voltage ) and OUT (voltage) waveform when plug power adapter for your reference (when battery run out of power condition)

      And our current probe is not in our lab,I don't provide current waveform..

Best Regards.

Hi Ting,

Wanted to clarify before proceeding, is this with the system connected at OUT? 

Hi Anthony:

  Our system power is 3.3V from OUT to 3.3V through LDO regulator..

  If I disable /CE function after our MCU boot ready, is it useful....

Best Regards.

Hi Ting,

Based on your waveform, the device looks to be operational with OUT at 4.4V and BAT in fast charge mode. Can you clarify the issue and give waveforms for when your system is working and not working? 

Hi Ting,

Any updates?
