A modified charge cycle, with the thermal loop active, is shown here:
Figure 36. Typical Charge Cycle, Thermal Loop Active
The TPS65820 applies a precharge current Io(PRECHG) to the battery if the battery voltage is below the V(LOWV)
threshold, preconditioning deeply discharged cells. The charge current loop regulates the ISET1 pin voltage to an
internal reference value, VPRECHG. The resistor connected between the ISET1 and AGND pins, RSET, determines
the precharge rate.
The precharge rate programmed by RSET is always applied to a deeply discharged battery pack, independently of
the input power selection (AC or USB). The precharge current can be calculated as follows:
where:
KSET is the charge current scaling factor and VPRECHG is the precharge set voltage.
The constant charge current mode (fast charge) is set when the battery voltage is higher than the precharge
voltage threshold. The charge current loop regulates the ISET1 pin voltage to an internal reference value, VSET.
The fast charge current regulation point is defined by the external resistor connected to the ISET1 pin, RSET, as
shown in the following:
where:
VSET (2.5 V typ) is the voltage at ISET1 pin during charge current regulation and KSET = Charge Current
Scaling Factor.
The reference voltage VSET can be reduced via I
2C register CHG_CONFIG bits ISET1_1 and ISET1_0. V
SET can
be selected as a percentage (75%, 50% or 25%) of the original 2.5 V typ, non-attenuated VSET value, effectively
scaling down the charge current.
