PRODUCTION DATA
When termination conditions are met, a battery detection cycle is started. During battery detection, IDETECT is pulled from VBAT for tDETECT to verify there is a battery. If the battery voltage remains above VDETECT for the full duration of tDETECT, a battery is determined to present and the IC enters “Charge Done”. If VBAT falls below VDETECT, a “Battery Not Present” fault is signaled and battery detection continues. The next cycle of battery detection, the BQ2416xx turns on IBATSHORT for tDETECT. If VBAT rises to VDETECT, the current source is turned offand after tDETECT, the battery detection continues through another current sink cycle. Battery detection continues until charge is disabled or a battery is detected. Once a battery is detected, the fault status clears and a new charge cycle begins. Battery detection is not run when termination is disabled.
