FUNCTIONAL DESCRIPTION
bq27010, bq27210
SLUS707B–APRIL 2006–REVISED JANUARY 2007
The bqJUNIOR determines battery capacity by monitoring the amount of charge input to or removed from a
Li-Ion or Li-Pol battery. The bqJUNIOR measures discharge and charge currents, monitors the battery for low
voltage thresholds, and compensates for self-discharge, aging, temperature, and discharge rate. Current is
measured across a small value series resistor between the negative terminal of the battery and the pack ground
(see R
S
in
Figure 3
). Available capacity is reported with a resolution of 3.57 μVh. Time-To-Empty reporting in
minutes at standby, actual, and at-rate currents allows the requirements for host-based calculations to be greatly
reduced or eliminated; reading a single register pair provides useful and meaningful information to the end user
of the application.
