NOTE
The device can be configured to support a 100-kΩ NTC (B = 3960) by setting the the
NTC_TYPE bit in register CHGCONFIG1 to 1. However it is not recommended to do so. In
sleep mode the charger continues charging the battery but all register values are reset to
default values, therefore the charger would get wrong temperature information. If 100 kΩ
NTC setting is required, please contact the factory.
