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.
