description: |
The LTC ® 4162-L is an advanced monolithic synchronous step-down switching
battery charger and PowerPath (TM) manager that seamlessly manages power
distribution between input sources such as wall adapters, backplanes, solar
panels, etc., and a rechargeable Lithium-Ion/Polymer battery.
Specifications about the charger can be found at:

Number of battery cells. If not provided, will be obtained from the chip
once the external power is applied. Omit this when the number of cells
is somewhat dynamic. Without it, several measurements will return 0 until
the charger is connected to an external supply.
