+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

+ iin_limit_active

+
+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.
+
+ Access: Read, Write
+
+ Valid values: 0 (disable) or 1 (enable)
