PRODUCTION DATA.
Once the OUT terminal goes above VRCH, (reaches voltage regulation) and the current tapers down to the termination threshold (10% of the fast charge current), the CHG terminal goes high impedance and a battery detect route is run to determine if the battery was removed or the battery is full. If the battery is present, the charge current will terminate. If the battery was removed along with the thermistor, then the TS terminal is driven high and the charge enters TTDM. If the battery was removed and the TS terminal is held in the active region, then the battery detect routine will continue until a battery is inserted.
