When charge is enabled , the device automatically completes a charging cycle according to the settings on VSET, ISET and CHM_TMR pins without any intervention. The lithium-based charging cycle is automatically terminated when the charging current is below termination threshold, charge voltage is above recharge threshold, and device is not in thermal regulation (TREG). When a full battery is discharged below the recharge threshold (VRECHG), the device automatically starts a new charging cycle. After charge is done, toggling the input supply or the CE pin can initiate a new charging cycle.
