Other Parts Discussed in Thread: BQ76940, BQ76952
TI Experts,
I see BQ76200 can support high side switch with BQ76940. One question need your help:
In BQ76200 datasheet "Charge Pump Control" chapter, it said "Otherwise, the CHG and DSG do not turn on if the charge pump voltage fails to ramp up above UVLO."
I wonder, if Vbat is lower than 8V or somewhat threhold value, can charge pump ramp up above Vbat by 9V?
Since I tested if BQ76952 is connected with 7V voltage, the charge pump still can ramp up above Vbat by 12V.
I'm sincerely hope to your comments!
