Notes:
5. Negative current is current flowing from the battery to VBUS (discharging the battery).
6. Q2 always turns on for 60ns, then turns off if current is below ISYNC.
7. Guaranteed by design; not tested in production.
8. This tolerance (%) applies to all timers on the IC, including soft-start and deglitching timers.
