BQ24650: 30-minute precharge timer issue

Part Number:BQ24650

Question 1: In the datasheet there are several places call out VRECH, however, there’s no VRECH definition. What is VRECH? Is it the same as VRECHG?

Question 2: It requires VBF>VLOWV (1.55V) within 30 minutes, or it enters the fault condition. How does it get out of the fault mode? From Figure 14, it seems that it sticks in an infinite loop.

If we have a large battery or when the supply current list small/limited, we could be at risk if we can’t reach VFB > VRECH (what’s the numerical value?) within 30 minutes at the rate of 1/10 of fast charge current.

Thanks
