Hi
We are implementing your bq27501 battery monitor. We are having problems with the RID function... The monitor does not seem to react to the change in RID resistor. Could you please explain when this test is done and how the test is performed. ie.... Is it done only apon battery insertion or a reset? Or is there a continuous monitoring of the RID input?
How can we test whether the test is being performed or not? ie. If we scope the RID input pin... What values should we be reading on the scope and when will these values occur?
The pull up resistors whithin the ic.... if we have a 2 batterey pack types... one with a RID value of 220KOhms and one with 110KOhms, How sould the pullups be configured... weak, strong or NO pullup
We would appreciate any help you could offer
Best regards Roger Yttervik
