max17048_battery
~~~~~~~~~~~~~~~~
Required properties :
- compatible : Should contain "maxim,max17048".
- alert-threshold : Alert threshold. in %(percentage). 0~32.
- one-percent-alerts : 1% alert mode control.
1=enable, 0=disable.
- valert-max : Maximum Voltage threshold for alert. in mV.
This value should be multiple of 20mV. 0~5100mV.
- valert-min : Minimum voltage threshold for alert. in mV.
This value should be multiple of 20mV. 0~5100mV.
- vreset-threshold : Voltage threshold for reset. in mV.
This value should be multiple of 40mV. 0~5080mV.
- vreset-disable : Voltage threshold reset control.
1=disable, 0=enable
- hib-thhreshold : Threshold to enter hibernate mode. in 0.208%/hr. 0~255.
If the absolute value of CRATE is less than this for longer than 6min,
the IC enters hibernate mode.
- hib-active-threshold : Hibernate active threshold. in 1.25mV. 0~255.
If at any ADC sample is greater than this, the IC exits hibernate mode
and 6min timer is reset.
- bits : 19-bit or 18-bit model.
19=19-bit model, 18=18-bit model.
This value is depends on custom model.
- rcomp : Starting RCOMP value. 0~255.
This value is depends on custom model.
- rcomp-seg : RCOMPSEG register.
This value is depends on custom model.
- soccheck-a : SOC check low value. in %(percentage).
This value is depends on custom model.
- soccheck-b : SOC check high value. in %(percentage).
This value is depends on custom model.
- ocvtest : OCV test value.
This value is depends on custom model.
- data-tbl : Custom model data. This should be 64 entries(64 bytes).
This value is depends on custom model.
Contact Maxim for details on how to configure the values involved with custom model.
Optional properties :
- use-ac : Use AC charging.
If not present, AC charging will not be used.
- use-usb : Use USB charging.
If not present, USB charging will not be used.
