Supercapacitors does not require trickle charge or pre-charge when their voltage is low. Supercapacitors can be charged with fast charge current even when the voltage is zero. The termination current setting is also not required. For setting EN_PRECHHARGE bit to 0 disables both trickle charge and pre-charge. The charge timer can be disabled as well. To use optimum charge current, the settings in Table 5-1 can be used.
