Device will be transition from normal Buck-Boost operation to PTM operation by:
?
Set REG0x31[7] = 0, to disable the EN_EXITILIM.
?
Set REG0x30[8] = 1.
?
Set REG0x30[2] = 1.
?
Ground ILIM_HIZ pin.
Device will transition out of PTM mode with host control by:
?
Set REG0x30[2] = 0.
?
Pull ILIM_HIZ pin to high.
?
Device exits PTM to buck-boost operation if tripping VinDPM.
?
Device exits PTM to buck-boost operation under fault conditions (for examples ACOC, TSHUT, BATOC,
BATOV).
1、According to the above from datasheet, need host a GPIO control to change ILIM_HIZ PIN low or high to eanble or disable PTM Mode? Can BQ25710 control this PIN by setting reg?
2、Should the charge bat function be enable during PTM mode?
Ps: system input 19V，Bat 4cell。
