1. The AAT3681A output charge voltage is specified over the 0° to 70°C ambient temperature range; operation over the -25°C to +85°C

temperature range is guaranteed by design.

2. Achievable charge current may be limited by power dissipation capability of the package under certain operating conditions. See

“Thermal Considerations” section of this datasheet.
