Figure 5. Power Mode Flow Chart

During normal operation, the device is in active mode, which corresponds to the highest power consumption.

Normal gas gauging is performed in this mode. If system requirements mandate that bqJUNIOR should not

is required on the bqJUNIOR side of the system. The resistor value chosen should be small enough to force a

logic 1 even with the internal pulldown current and any external ESD protection circuitry loading.
