The ATmega16HVB/32HVB is a monitoring and protection circuit for 3 and 4-cell Li-ion applications
with focus on high security/authentication, low cost and high utilization of the cell energy.
The device contains secure authentication features as well as autonomous battery protection
during charging and discharging. The External Protection Input can be used to implement other
battery protection mechanisms using external components, e.g. protection against chargers with
too high charge voltage can be easily implemented with a few low cost passive components.
The feature set makes the ATmega16HVB/32HVB a key component in any system focusing on
high security, battery protection, high system utilization and low cost.
