Development Bq20z75 without external charger

Other Parts Discussed in Thread: BQ2000

Hi,

I am working with GAS GAUGE bq20z75, charger Bq2000 and Voltage protection bq29212.

Pack Battery 3 cell's 2200mAh (3S1P); 

Charger/Discharge Operation 0.5C ;

Source: 15Vdc 1A


Would I  like some information, if it is possible to developlment bq20z75 without extern charger?

What does it take care to work without charger? And how does the bq20z75 configuration right ?


Because I have read the documents of Bq20z75( Charge Control Features pg 11 SLUSA22 –DECEMBER 2009) and with outher  (3.4 Charge Control pg 119 SLUA404 – December 2006) ,  it has possible configurantion and register of charger/discharge bq20z75.

If it isn't possible, which are they specification of charger that o Fuel gauge bq20Z75 doesn´t have it?

I have read other documents Bq20z75, it doesn´t say to use together with charger.

Best regards,

Rogerio Dias
