  • Can I use an input capacitor with a capacitance less than the recommended value?
    • A pass-through current flows during detection. The input capacitor serves to mitigate the voltage drop associated with this current. (The drop will be substantial if voltage is supplied to the IC via a voltage divider.)
      The pass-through current may vary based on the customer's usage conditions, external resistance value, and detection voltage startup speed.
      Once the voltage drop exceeds the detection hysteresis vibration may occur (please refer to the technical notes).
      Therefore, please carefully select the resistor and capacitor that minimizes this voltage drop.
