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 VDD and VSS pin for stabilization.
• A capacitor (CL) 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 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.
