Dear TI member,
When BQ25895m is used in boost mode(OTG enable and PMID=5.1V), and battery is discharged status.(no adaptor or USB in)
I have changed TS input to low temp and high temp using resistor during boost mode, then I find the VREGN will be discharged to 0V and boost mode is disabled and IC goes to shipping mode.
I have used QON pin when IC is shipping mode. It is well if I set BATFET_Disable bit (REG09[5]) to 1 via I2C.
But it can't recover when IC goes to shipping mode from boost mode in temperature is in the low temp or high temp even though the temperature is returned to normal.
But the datasheet write down as below,
"For battery protection during boost mode, the device monitors the battery temperature to be within the VBCOLDx to
VBHOTx thresholds unless boost mode temperature is disabled by setting BHOT bits to 11. When temperature is
outside of the temperature thresholds, the boost mode and BATFET are disabled and BATFET_DIS bit is set to
reduce leakage current on PMID. Once temperature returns within thresholds, the host can clear BATFET_DIS
bit or provide logic low to high transition on QON pin to enable BATFET and boost mode."
Could please let me know how I can solve this problem?
Thanks,
JP.
