NFET driver characteristics
1. Measures NFET driver’s ability to switch OC/OD from 0V to specified output level with constant resistive load on the pin.
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 advance. If the FET is already enabled, the FET will be fully operational in the entire
voltage range of the device (4V to 18V).
ATmega16HVB/32HVB
Loads above this limit may cause OC/OD not reaching the specified level. Drive capability is highly temperature dependent.
