BQ25798: REGN LDO is Not Turning ON

Part Number: BQ25798

Tool/software:

Hello,

We have encountered an issue where REGN LDO is not turning ON and Batteries are not getting charged.

We have measured the voltages at various test points they were as follows

Input Voltage = 5V
Current Consumption = 0.00A
REGN = 0.018V
PMID = 4.98V
SDRV = 0V
PROG = 0V
TS pin = 0V
HiZ = 0V

But, We were able to communicate with BQ25798 on I2C. Where we read all the fault registers but no faults has occured. We have also read the EN_HiZ it is in Reset (0) State. Also able to read the ADC Vbus voltage someimes.

Please provide a solution for this issue about REGN LDO not turning ON. Let us know if you need more details

Thank You!
