1.1.4	Battery protection detection levels
The characterization of the Deep Under-voltage, Over-current and Short-circuit detection levels;深度低电压，过流，短路
show that the actual真实 thresholds are typically 10% below the numbers given in the datasheet. This；
is caused by parasitic elements in the layout that are not included in the simulation models.
The spread 展开in these thresholds开始 are however无论如何 in the expected预期范围 range of +/-5% for Over-current
detection levels, and +/-3% for Deep Under-voltage detection levels.

Detailed characterization data列出描述数据 will be given in the Analog characterization report.类似描述报告

Workaround for ATmega406 rev. D:工作区
As long as the actual range for these detection levels covers the required range for the
application used for qualification of ATmega406 rev. D, a correct detection level can always be found.

ATmega406 fix:
We assume 设想that it is sufficient to update the datasheet with the actual detection levels found
during characterization. If not, the thresholds can be tuned to better fit the specification in the datasheet.
