+description: |
+  The LT8491 is a buck-boost switching regulator battery charger that implements
+  a constant-current constant-voltage (CCCV) charging profile used for most
+  battery types, including sealed lead-acid (SLA), flooded, gel and lithium-ion.
+
+  Specifications about the charger can be found at:
+    https://www.analog.com/en/products/lt8491.html
