PWM OUTPUT TEMPERATURE SENSOR IC
S-5855A Series
Rev.1.2_01
 Precaution
• Note that this IC may itself heat depending on a connected load to the output pin, resulting in error in measuring
temperature.
• Set a capacitor (CIN) of approx. 0.1 μF between the VDD pin and VSS pin for stabilization as close to IC as possible.
• Connect a capacitor CFREQ for oscillation frequency as close to IC as possible.
• Leakage current applied on the CF pin may cause error in the output duty ratio. Do not connect other components than
CFREQ.
• Since the error of the output duty ratio may become large depending on an application circuit or the design of a board
pattern on this IC, perform thorough evaluation with the actually mounted model in the case of use.
• The application conditions for the input voltage, output voltage, and load current should not exceed the package power
dissipation.
• 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.
