APPLICATION INFORMATION(Cont.)
Automatic charge-rate compensation setup requires the following information:
* Total impedance of battery pack (Z(PACK))
* Maximum charging current (I(REG))
The voltage drop across the internal impedance of battery pack, V(Z), can then be calculated using the following
equation:

Where V(COMP) is the voltage on COMP pin. This voltage is referenced to VCC in current sensing configuration.
V(PACK) is the voltage across the battery pack.
The values of R(COMP1) and R(COMP2) can be calculated using the following equation:
