Derating

The functionality of the charge and control unit is designed for a wide temperature range. In
order to protect the charge and control unit, it should be powered down at temperatures
higher than 60 °C in order to prevent overheating of the device.

The maximum output current is provided up to a temperature of 60 °C. In addition, the output
rated current must be lowered by 2.5% per Kelvin.

Illustration 11: Temperature behavior of the output rated current

The maximum charging current is provided up to a temperature of 50 °C. In addition, the
rated output current is lowered by 3% per Kelvin.
