2. Delay Circuit
2-1. Delay Time
The delay circuit delays the output signal from the time at which the power voltage (VDD)
exceeds the release voltage (
+VDET) when VDD is turned on. The output signal is not delayed
when the VDD goes below the detection voltage (–VDET). (Refer to Figure 11.)
The delay time (tD) is a fixed value that is determined by a built-in oscillation circuit and
counter.
2-2. DS Pin (ON/OFF Switch Pin for Delay Time)
The DS pin should be connected to Low or High. When the DS pin is High, the output delay
time becomes short since the output signal is taken from the middle of counter circuit (Refer to
Figure 16).
