Hi,

Could you tell me about DPPM?

When the DPPM pin is floating state,
Charge is disabled but OUT is output?
Customer wants to interrupt the current of "IN→BAT" through the current of "IN→OUT".

Best Regards,
Yusuke

Yusuke-San,
This app note here provides a lot of detail about this feature: www.ti.com/.../slua400a.pdf
When DPPM pin is floating, charging is disabled but OUT is still enabled. If the customer wants to control charging, they can look into the BQ24076 or BQ24078 which allows the customer to turn on or turn off the BAT FET.
