The ATmega8HVA/16HVA is a monitoring and protection circuit for 1-cell and 2-cell Li-ion applicationswith focus on high security/authentication, accurate monitoring, 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 chip allows very accurate
accumulated current measurements using an 18-bit ADC with a resolution of 0.84 μV. The feature
set makes the ATmega8HVA/16HVA a key component in any system focusing on high
security, battery protection, accurate monitoring, high system utilization and low cost.
