Figure 3. Equivalent Circuit Block Diagram
Sample Application Circuit
td = 100 x Cd (mF) [ms]
NOTES:
1. When Cd ≥ 10 mF, the capacitor may not discharge completely, causing td to be made shorter than a set value. In this case,
connect high−speed diode (DS442) across pin 2 (anode side) and pin 5 (cathode side)
2. Connecting a pull−up resistor to the reset output externally allows sink current up to 4 mA to flow.
