PRODUCTION DATA
(1) tD (no cap) is
included in tSTRT time delay. If tD delay is
programmed by an external capacitor connected to the CTR pin then
tD programmed time
is added to
the startup time.
(2) Be advised, in some
instances, the VDD falling slew rate in Figure 6-1 can be slow or such that VDD decay time is much larger than the SENSE
delay time (tD-SENSE) time allowing
the output to assert. If the VDD falling slew rate is much faster than the
(tD-SENSE), the output appears to be not
asserted.
