1 All limits at temperature extremes are guaranteed via correlation using standard statistical quality control (SQC) methods.
2 Guaranteed by design, not tested in production.
3 If SYNC function is used, then fSYNC must be greater than fCT but less than 120% of fCT.
4 VCS = (VCS+) − (VCS−).
5 Accuracy guaranteed by ISET input, programming function accuracy specification.
6 System current sense is active during shutdown.
7 Load current is supplied through SYS+ pin.
8 Guaranteed output current from 0 to minimum specified value to maintain regulation.
9 VBAT < 93% of final or VCS > 25 mV.
10 VBAT ≥ 93% of final or VCS ≤ 25 mV.
