BQ27530-G1: Using the gauge with a battery without thermistor.

Part Number: BQ27530-G1
Other Parts Discussed in Thread: BQ24161, BQ27530EVM, BQSTUDIO


Is it possible to use the gauge with a battery which doesn't have a thermistor? Reading the gauges' datasheet I would say it isn't. But on the schematic included in the BQ27530EVM (SLUUA09B), on page 3, it is stated "Only needed when the Gauge is monitoring the battery NTC." right next to a group of parts related to the temperature sensing. So, there is some setting on the gauge registers so the gauge can be used to control the BQ24161 in host mode but with a battery without thermistor?
