PWM OUTPUT TEMPERATURE SENSOR IC

S-5855A Series

Rev.1.2_00

Seiko Instruments Inc.

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 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.
