Component from BMS circuit

[maxmad]

Looking for the part inside the red circle.


It is from a laptop battery pa06062 BMS circuit with BQ40Z551 controller.
Covered with white glue, probably gone while removing the glue.

One pin connected to V+ of the battery cells.
Other to pin 7 of Q5K FY 095.


Probably a battery protection IC with 1K resistors for each cell but can anyone identify this IC?

The component may be a pull-up, or may be a ptc to detect the two MOSFETs overheating.

It is similar to S8264A but not the same.
Pins 5-6 are grounded.

I made more measurements and almost find the resistor's sequence.
But still the missing component at pin 7 is a mystery till find the exactly same IC.

According to the datasheet, the mystery component is a PTC, or a resistor in the range of 0 to 500 ohms.
