■ TIMING CHART
○
1
When the input voltage is up to about 0.8V, some voltage is outputted at the reset output because the NJM78LR05
operation is unstable.
○
2
When the input voltage goes over about 0.8V, the reset output becomes “L”.
○
3
The output voltage is rising up with the input voltage.
○
4
When the output voltage goes over (V
RT
+V
RTH
), the delay circuit of reset output activates.
V
RT
: Reset Threshold Voltage
V
RTH
: Reset Threshold Hysterisis Voltage
○
5
After the reset output delay time td has passed, the reset output becomes “H”.
○
6
The output voltage is falling down with the input voltage.
○
7
When the output voltage is less than V
RT
, the reset output becomes “L”.
