hi Dustin,

The only single cell gauges with an AFE which we have are the bq27750 and the bq27742. None of them has the sys pres pin but you should be able to implement that on your host controller.

thanks

Hi Onyx :
thanks for your response.
do we have plan to develop this kind of IC ?

not at this time. There is nothing special about the system pres feature. It is just a matter of having a comparator to determine if a pin is low or high when the battery is inserted. The Thermistor that comes with the pack can be used such that when conneceted it pulls a gpio pin on a controller low and that is used to detect sys present

thanks
Onyx
