NJM78LR05BD/CD/BL/CL

is the NRND product.

■ 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 (VRT+VRTH), the delay circuit of reset output activates.

VRT : Reset Threshold Voltage

VRTH : 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 VRT, the reset output becomes “L”.
