Hi Team,

may we know if there is any problem with this schematic? because the REGN pin does not output +5v.

.could help double check this schematic ? thanks.

Hi Tommy,

For REGN voltage, the following must be true

1. VAC voltage above VAC_OK and charge is enabled in forward mode.

2. BAT voltage above 3 V in Reverse mode and Reverse Mode is enabled (EN_REV = 1)

Is either true?

Regards,

Jeff
