Other Parts Discussed in Thread: TPS7A4001, BQSTUDIO, BQ34Z100
I have made few changes in bq34z100-G1 as below:
1. For input of TPS7A4001, now I use BAT5(Bq34_Vdd) as in attached schematic. This regulator can work with input range 7.5V-25V to give output as 4V, so I think this would be ok also.
This is because, since regulator's input max is 100V, close to max battery voltage of 84V. In motor applications, spikes would be high at 100A current or higher. I want to keep safety margins.
Do you think it is ok?
2. Also at BAT pin of bq34z100-G1, the mosfet circuit has been removed, & simple divider network is used with a jumper settings to connect to one of following :BAT5, BAT10, BAT15, BAT20
Without mosfets there will be be small current wasted continuously, but this does not effect much, since this ckt is meant for high capacity batteries only. In current system, we are using 72V/80Ah system.
Do think it is ok, or it could effect some measurement accuracies?
3. Where Can I found the TRM manual for bq34z100-G1. I need to fill up the data flash. I am using bqstudio 1.3.52.
4. Also can you provide app note for making golden image for bq34z100-G1. On E2E forum, I found slua334b, but this is for bq20xxx devices.
Ckt attached is not complete. It shows only portion of complete ckt.
