Caution The above connection diagram will not guarantee successful operation. Perform thorough
evaluation using actual application to set the constant.
„ Precautions
• Set a capacitor (C_IN) of about 0.1 µF between VDD and VSS for stabilization.
• A capacitor (C_L) of about 1 µF should be connected to the DET pin to prevent malfunction caused by noise due to the
power being on.
• Do not connect a capacitor to the RT pin (leave the RT pin open). Otherwise, this IC may oscillate.
• Do not apply an electrostatic discharge to this IC that exceeds the performance ratings of the built-in electrostatic
protection circuit.
• SII 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.
