PRODUCTION DATA
A new charge cycle is started when a good power source is applied, performing a chip disable/enable (TS pin), exiting Termination and Timer Disable Mode (TTDM), detecting a battery insertion or the OUT voltage dropping below the VRCH threshold. The CHG pin is active low only during the first charge cycle, therefore exiting TTDM or a dropping below VRCH will not turn on the CHG pin FET, if the CHG pin is already high impedance.
