BATTERY INTERFACE AND POWER PATH MANAGEMENT
• A bi-directional source in the form of a rechargeable single
system host is responsible for notifying the 900841 of what
type of input source it is connected to, by setting the
maximum current the charger can draw from the input
source (for example: 0.5 A USB or 1.8 A power source
device).
