+title: Binding for LTC2941, LTC2942, LTC2943 and LTC2944 battery fuel gauges
+
+description: |
+ All chips measure battery capacity.
+ The LTC2942 is pin compatible with the LTC2941, it adds voltage and
+ temperature monitoring, and is runtime detected. LTC2943 and LTC2944
+ are software compatible, uses a slightly different conversion formula
+ for the charge counter and adds voltage, current and temperature monitoring.

-binding for LTC2941, LTC2942, LTC2943 and LTC2944 battery gauges
-
-All chips measure battery capacity.
-The LTC2942 is pin compatible with the LTC2941, it adds voltage and
-temperature monitoring, and is runtime detected. LTC2943 and LTC2944
-is software compatible, uses a slightly different conversion formula
-for the charge counter and adds voltage, current and temperature monitoring.
-
-Required properties:
-- compatible: Should contain "lltc,ltc2941", "lltc,ltc2942", "lltc,ltc2943"
- or "lltc,ltc2944" which also indicates the type of I2C chip attached.
-- reg: The 7-bit I2C address.
-- lltc,resistor-sense: The sense resistor value in milli-ohms. Can be a 32-bit
- negative value when the battery has been connected to the wrong end of the
- resistor.
-- lltc,prescaler-exponent: The prescaler exponent as explained in the datasheet.
- This determines the range and accuracy of the gauge. The value is programmed
- into the chip only if it differs from the current setting. The setting is
- lost when the battery is disconnected.
-
-Example from the Topic Miami Florida board:
-
- fuelgauge: ltc2943@64 {
- compatible = "lltc,ltc2943";
- reg = <0x64>;
- lltc,resistor-sense = <15>;
- lltc,prescaler-exponent = <5>; /* 2^(2*5) = 1024 */
- };
