9.3.3 Control State Diagram for System Implementation

The device being charged will need to communicate with the adapter to control the current being delivered to the BQ25968. This is accomplished by using the adjustable protection and alarm settings in the BQ25968, and communicating to the wall charger (or power bank or car charge adapter) as shown in Figure 9-3. The availability of the alarms are dependant on the presence of the input supply and the charge state, which is shown in Table 9-1.
