Hi.

I have a question for BQ24100.

When BQ24100 is Off status(Vin = 0V, BAT = On, #CE = GND), STAT1 is open?? or pull-down??

Plz let me know default Status of STAT1.

Thanks

Off means the LED is off and the internal "STATUS" FET is off with a high impedance output.

Another question.

If disable Temperature Sense function, Leave TP(12) pin floating???

Disabling may be the wrong word, since the TS circuit can't be disabled....it is really using a resistor divider to fix the TS input voltage to a normal operating value, thus making the IC think that the temperature is always in a normal range.

Dear Charles Mauney,

i am trying to implement the resistor divider to fix the TS input voltage to a normal operating value, thus making the IC think that the temperature is always in a normal range in bq24104. could you please guide me on how to do this.

Thank you
