APPLICATION INFORMATION(Cont.)

QUALIFICATION AND PRECHARGE

When the battery is present and power is applied, the UTC UB2012 starts a charge-cycle. Charge qualification

is affected by battery temperature and voltage. If the battery temperature is out of the VTS1 to VTS2 range; the UB2012

will suspend charge. In addition, if the battery voltage is below the precharge threshold V(min), the UB2012 uses

precharge to condition the battery. The conditioning charge rate I(PRECHG) is set at approximately 10% of the

regulation current, and the conditioning current minimizes heat dissipation in the external pass-element during the

beginning of charge, refer to Figure 3.
