The battery charger of the multifunction device RT5033 has to be instantiated
|
||
|
|
under sub-node named "charger" using the following format.

|
|
Phandle to the monitored battery according to battery.yaml. The battery
|
||
|
|
node needs to contain five parameters.
|
||
|
|
|
||
|
|
precharge-current-microamp:
|
||
|
|
Current of pre-charge mode. The pre-charge current levels are 350 mA
|
||
|
|
to 650 mA programmed by I2C per 100 mA.
|
||
|
|
|
||
|
|
constant-charge-current-max-microamp:
|
||
|
|
Current of fast-charge mode. The fast-charge current levels are 700 mA
|
||
|
|
to 2000 mA programmed by I2C per 100 mA.
|
||
|
|
|
||
|
|
charge-term-current-microamp:
|
||
|
|
This property is end of charge current. Its level ranges from 150 mA
|
||
|
|
to 600 mA. Between 150 mA and 300 mA in 50 mA steps, between 300 mA and
|
||
|
|
600 mA in 100 mA steps.
|
||
|
|
|
||
|
|
precharge-upper-limit-microvolt:
|
||
|
|
Voltage of pre-charge mode. If the battery voltage is below the pre-charge
|
||
|
|
threshold voltage, the charger is in pre-charge mode with pre-charge
|
||
|
|
current. Its levels are 2.3 V to 3.8 V programmed by I2C per 0.1 V.
|
||
|
|
|
||
|
|
constant-charge-voltage-max-microvolt:
|
||
|
|
Battery regulation voltage of constant voltage mode. This voltage levels
|
||
|
|
from 3.65 V to 4.4 V by I2C per 0.025 V.
