Other Parts Discussed in Thread: BQ25155
Hello.
In the datasheet (BQ25150/BQ25155 ) there is a parameter VS Threshold hysteresis = 4.7mV. I think it is very small. If the TS susstem supplies bias current Its_bais = 80uA and NTS voltage changes to 4.7mV, the NTC circuts resistance will change about ( 4.7mV/ 80uA ) 59 Ohm . It corresponds to change by less 1 С° for 10K NTC near 45С°. I gess it can destabilize my device by frequent switching.
Is there a way to increase hysteresis voltage?
