2. Power-on reset circuit
A power-on reset circuit can be constructed using Nch open-drain output product of S-1000 Series.
Remark When the power rises sharply as shown in the Figure 28 left, the output may go to the high level for an instant
Caution The above connection diagram and constants do not guarantee correct operation. Perform sufficient
*1. R should be 75 kΩ or less, and C should be 0.01 μF or more to prevent oscillation.
*2. Diode Di instantaneously discharges the charge stored in the capacitor (C) at the power falling, Di can be removed
If C is not connected, R should be 800 Ω or less.
