The BQ7718 datasheet is bit confusing when looking at the "Device Comparison Table" in section 5. I believe the device only comes in two output drive variants:
- "CMOS" with active push-pull to device VSS and VDD
- "NCH Active Low, Open-Drain" with active pull down to device VSS but requiring external pull-up
The table appears to indicate a third variant for the BQ771708 and BQ771815 with the description of only "NCH Active Low". Is this just an over-sight in the table or is this a third output drive type with active pull-down, internal passive pull-up and possibly with different protection clamping?
