DYNAMIC TIMER FUNCTION
charge pre-charge safety timers programmed user detect fault condition charge cycle duration exceeds total time expected under normal conditions. expected charge time usually calculated based fast charge current rate. When thermal loop activated charge current reduced, bq2406x activates dynamic timer control, internal circuit that slows down safety timer's clock frequnency. dynamic timer control circuit effectively extends safety time duration either precharge fast charge timer modes. This minimizes chance safety timer fault thermal regulation. bq2406x dynamic timer control (DTC) monitors voltage ISET during pre-charge fast charge, thermal regulation slows clock frequency proportionately change charge current. time duration based ripple counter, slowing clock frequency real time correction. circuit changes safety timers clock period based V(SET)/V(ISET) ratio (fast charge) V(PRECHG)/V(SET) ratio (pre-charge).

When voltage falls recharge threshold, either connection load battery battery removal, bq2406x begins battery absent detection test. This test involves enabling detection current, IDET(DOWN), period T(DETECT) checking battery voltage below pre-charge threshold, V(LOWV). Following this, precharge current, IDET(UP) applied period T(DETECT) battery voltage checked again above recharge threshold. Passing both discharge charging tests (battery terminal voltage being below pre-charge above recharge thresholds battery detection test) indicates battery absent fault STAT1 STAT2 pins. Failure either test starts charge cycle. absent battery condition voltage rises falls between V(LOWV) VO(REG) thresholds indefinitely. operation flowchart more details this algorithm. desired power system load without battery, recommended float which puts charger mode (disables termination). battery absent detection function disabled when termination disabled. bq2406x provides small battery leakage current, IBAT(DONE) typical), after termination pull down voltage event battery removal. leakage higher than this pulldown current, then voltage remains above termination battery-absent state will detected.
