| 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. |
