Part Number: BQ27750
Hello TI team,
I plan to use the BQ27750 for a battery monitoring of the 18650, and now I have some puzzles about the schematic.
[ Question ]
1. I integrated the TPS61072 5V boost chip and BQ27750 on a single board. Is the BAT_PWR (PACK+ in BQ27750 IC ) of the schematicas the input of the TPS61072 IC or the VCC_BAT(Cell BAT+) as the input of the TPS61072 IC? The schematic is as follows, which design is more reasonable, or you have better suggestions.
2. If VCC_BAT is the input to the TPS61072 IC, what should I do with PACK+PACK- in the BQ27750 schematic?
3. If it is convenient, please help check if the schematic has any deficiencies.
Thank you in advance.
