NFET Driver Characteristics
The NFET drivers require a minimum total cell voltage of 6V or higher or a charger connected to turn-on the FETs. Note that this
limit only applies if the FET is disabled in advanced. If the FET is already enabled, the FET will be fully operational in the entire
voltage range of the device (4-25V).
