+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.

+    description: |
+      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.
