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.
|
|
|

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.
