What: /sys/class/power_supply/ltc4162-l/charge_status
Date: Januari 2021
KernelVersion: 5.11
Description:
Detailed charge status information as reported by the chip.
Access: Read
Valid values:
ilim_reg_active
thermal_reg_active
vin_uvcl_active
iin_limit_active
constant_current
constant_voltage
charger_off
What: /sys/class/power_supply/ltc4162-l/ibat
Date: Januari 2021
KernelVersion: 5.11
Description:
Battery input current as measured by the charger. Negative value
means that the battery is discharging.
Access: Read
Valid values: Signed value in microamps
What: /sys/class/power_supply/ltc4162-l/vbat
Date: Januari 2021
KernelVersion: 5.11
Description:
Battery voltage as measured by the charger.
Access: Read
Valid values: In microvolts
What: /sys/class/power_supply/ltc4162-l/vbat_avg
Date: Januari 2021
KernelVersion: 5.11
Description:
Battery voltage, averaged over time, as measured by the charger.
Access: Read
Valid values: In microvolts
What: /sys/class/power_supply/ltc4162-l/force_telemetry
Date: Januari 2021
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).
Access: Read, Write
Valid values: 0 (disabled) or 1 (enabled)
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.

Valid values: 0 (disable) or 1 (enable)
