Caution The above connection diagram will not guarantee successful operation. Perform thorough evaluation
using actual application to set the constant.
 Precautions
• If power impedance is high, the S-5844A Series may malfunction due to voltage drop caused by feed-through current.
Set wire patterns carefully for lower power impedance.
• It is recommended to set a capacitor (CIN) of 0.1 μF or more between the VDD pin and VSS pin for stabilization.
• The S-5844A Series may malfunction if the power supply voltage changes suddenly.
• The S-5844A Series is more easily affected by disturbance or noise if the TEST pin is left open.
• It is recommended to set a capacitor (CL) of about 0.1 μF for the DET pin to prevent malfunction caused by the noise
when the power supply is applied.
• The S-5844A Series may malfunction if the power supply voltage is lower than the minimum operation voltage.
• 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.
