+description: |
+  MAX77643, MAX77654, MAX77658 and MAX77659 devices are a family of ADI PMICs
+  providing battery charging and power supply solutions for
+  low-power applications.
+
+  MAX77643 is a Power Management IC with 1 LDO regulator.
+
+  MAX77654 is a Power Management IC with 2 LDO regulators and 1 charger.
+
+  MAX77658 is a Power Management IC with 2 LDO regulators, 1 charger
+  and 1 fuel gauge.
+
+  MAX77659 is a Power Management IC with 1 LDO regulator and 1 charger.
