|
-----------
|
|
|
|
The MAX1704x are ultra-compact, low-cost, host-side fuel-gauge systems for lithium-ion (Li+) batteries in handheld and portable equipment.
|
|
|
|
* ``MAX17043``: single lithium cell
|
|
* ``MAX17044``: dual-cell 2S pack.
|
|
* ``MAX17048``: single lithium cell
|
|
* ``MAX17049``: dual-cell 2S pack.
|
|
|
|
Datasheets:
|
|
|
|
* `MAX17043-MAX17044.pdf <https://datasheets.maximintegrated.com/en/ds/MAX17043-MAX17044.pdf>`_
|

|
|
|
|
The MAX17048 & MAX17049 are more sophisticated versions, which support a number of extra features like measuring the change rate in percent per hour to measure load or charge rate.

Configuration
|
|
--------------
|
|
|
|
Device Settings
|
|
^^^^^^^^^^^^^^^^
|
|
|
|
|
|
**Device**: Select the version of the MAX1704x:
|
|
|
|
* ``MAX17043``
|
|
* ``MAX17044`` - 2-cell version of the MAX17043 (full-scale range of 10V)
|
|
* ``MAX17048``
|
|
* ``MAX17049`` - 2-cell version of the MAX17048
|
|
|
|
**Alert threshold** : Set the MAX1704x's percentage threshold that will trigger an alert.
|
|
|
|
**Send Event on Alert** : Send an event, to be used in rules, when the alert is set. This can be cleared with ``max1704xclearalert``
|
|
|
|
Values
|
|
^^^^^^
|
|
|
|
* Voltage: The measured voltage of the cell(s).
|
|
* State of Charge (SoC): The percentage left of the cell.
|
|
* Alert: Whether or not an alert was triggered (e.g. SoC below set threshold)
|
|
* Rate: The change rate of the SoC in percent per hour. Negative value is a discharge, positive is charge rate. (MAX17048 & MAX17049 only)
