Specifications subject to change without notice.
V
Accuracy guaranteed by ISET INPUT, Programming Function Accuracy specification.
Guaranteed by design, not tested in production.
All limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.
If SYNC function is used, then f
System current sense is active during shutdown.
Load current is supplied through SYS+ pin.
