KernelVersion: 5.11
|
|
Description:
|
|
To save battery current, the measurement system is disabled if
|
|
the battery is the only source of power. This affects all
|
|
voltage, current and temperature measurements.
|
|
Write a "1" to this to keep performing telemetry once every few
|
|
seconds, even when running on battery (as reported by the online
|
|
property, which is "1" when external power is available and "0"
|
|
when the system runs on battery).

What: /sys/class/power_supply/ltc4162-l/arm_ship_mode
|
|
Date: Januari 2021
|
|
KernelVersion: 5.11
|
|
Description:
|
|
The charger will normally drain the battery while inactive,
|
|
typically drawing about 54 microamps. Write a "1" to this
|
|
property to arm a special "ship" mode that extends shelf life
|
|
by reducing the leakage to about 2.8 microamps. The chip will
|
|
remain in this mode (and no longer respond to I2C commands)
|
|
until some external power-supply is attached raising the input
|
|
voltage above 1V. It will then automatically revert to "0".
|
|
Writing a "0" to the property cancels the "ship" mode request.
|
|
The ship mode, when armed, activates once the input voltage
|
|
drops below 1V.
