+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.
