Caution The above connection diagram will not guarantee successful operation. Perform thorough evaluation
using actual application to set the constant.
 Precautions
• Set a capacitor (CIN) of 0.1 μF or more between the VDD and VSS pin for stabilization.
• Set a capacitor (CL) of about 1 μF for the DET pin to prevent malfunction caused by the noise when the power
supply is applied.
• The S-5841 Series may oscillate by setting a capacitor to the RT pin. Set the RT pin open in use.
• If the RT pin is short-circuited to VSS, the DET pin becomes active in the S-5841 Series.
• Fix the HYS1 pin and the HYS2 pin VDD or VSS in use.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• SII Semiconductor Corporation claims no responsibility for any disputes arising out of or in connection with any
infringement by products, including this IC, of patents owned by a third party.
