Hi,
I'm designing an uninterruptible power supply with 4x LiFePO4 cells and bq24630 as the battery charger.
My systems runs on 24V and so, there will be a step-up circuit/block to boost the battery voltage to 24V.
As the bq24630 has an power selector feature, I'm planning to use bq24630's BATDRV signal + P-ch MOSFET (BATFET) to switch the power from the output of the boost stage to the system power (instead of directly from the battery) when the ACPWR is down.
Thus, I wonder if there are any recommendations or comments to this type of application/configuration for bq24630. As, for instance, if this is valid application and if there are any any special considerations about how to feed the bq24630's VCC pin.
Many thanks and regards,
Gustav
