* tps65217 rev. G, p. 31 (see p. 32 for NTC schematic)
*
* The device can be configured to support a 100k 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 the wrong temperature
* information. If 100k NTC setting is required, please contact the
* factory.
*
* ATTENTION, conflicting information, from p. 46
*
* NTC TYPE (for battery temperature measurement)
* 0 – 100k (curve 1, B = 3960)
* 1 – 10k (curve 2, B = 3480) (default on reset)
