Description
Force Start Input Current Optimizer (ICO)
0 – Do not force ICO (default)
1 – Force ICO
Note:
This bit is can only be set only and always returns to 0 after ICO starts
Safety Timer Setting during DPM or Thermal Regulation
0 – Safety timer not slowed by 2X during input DPM or thermal
regulation
1 – Safety timer slowed by 2X during input DPM or thermal regulation
(default)
Force BATFET off to enable ship mode
0 – Allow BATFET turn on (default)
1 – Force BATFET off
JEITA High Temperature Voltage Setting
0 – Set Charge Voltage to VREG-200mV during JEITA hig temperature
(default)
1 – Set Charge Voltage to VREG during JEITA high temperature
BATFET turn off delay control
0 – BATFET turn off immediately when BATFET_DIS bit is set (default)
1 – BATFET turn off delay by t_{SM_DLY} when BATFET_DIS bit is set
BATFET full system reset enable
0 – Disable BATFET full system reset
1 – Enable BATFET full system reset (default)
Current pulse control voltage up enable
0 – Disable (default)
1 – Enable
Note:
This bit is can only be set when EN_PUMPX bit is set and returns to 0
after current pulse control sequence is completed
Current pulse control voltage down enable
0 – Disable (default)
1 – Enable
Note:
This bit is can only be set when EN_PUMPX bit is set and returns to 0
after current pulse control sequence is completed
