Description:
|
|
This entry allows enabling the sysoff mode of rt9467 charger
|
|
devices.
|
|
If enabled and the input is removed, the internal battery FET
|
|
is turned off to reduce the leakage from the BAT pin. See
|
|
device datasheet for details. It's commonly used when the
|
|
product enter shipping stage. After entering shipping mode,
|
|
only 'VBUS' or 'Power key" pressed can make it leave this mode.
|
|
'Disable' also can help to leave it, but it's more like to
|
|
abort the action before the device really enter shipping mode.
