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 VBAT < 95% of final or VCS > 80% of ISET programmed value.
9 VBAT ³ 95% of final and VCS £ 80% of ISET programmed value.
Specifications subject to change without notice.
