PRODUCTION DATA
The detection delay timers are based from an internal clock with a frequency of 10kHz.
If the over-discharge current is detected, but remains below the over-discharge short circuit detection threshold, the over-discharge detection conditions must be valid for a time greater than or equal to over-discharge current delay tOCCD time before the DOUT goes low to turn OFF the discharge FET. However, during any time the discharge overcurrent detection exceeds the short circuit detection threshold for a time greater than or equal to load circuit detection delay tSCCD, the DOUT pin goes low in a faster delay for protection.
