S-5852A Series www.sii-ic.com HIGH-ACCURACY DIGITAL TEMPERATURE SENSOR WITH THERMOSTAT FUNCTION © SII Semiconductor Corporation, 2015-2016 Rev.1.1_00 The S-5852A Series is a high-accuracy digital temperature sensor with thermostat function, which operates in 1.7 V to 3.6 V 2 voltage ranges. The S-5852A Series interfaces with exteriors via I C-bus and operates at 1.0 MHz maximum. The 2 temperature detection signal is output by using the thermostat function which can be set by the I C-bus. Moreover, a 2 substantial reduction in current consumption may be achieved by using the shutdown mode which can be set by the I C-bus. The operation of the S-5852A Series is explained in the user's manual. Contact our sales office for more information.

TRES[1:0] = "11" setting Precautions • Do not operate these ICs in excess of the absolute maximum ratings. Attention should be paid to the power supply voltage, especially. The surge voltage which exceeds the absolute maximum ratings can cause latch-up and malfunction. Perform operations after confirming the detailed operation condition in the datasheet. • Operations with moisture on this IC's pins may occur malfunction by short-circuit between pins. Especially, in occasions like picking this IC up from low temperature tank during the evaluation. Be sure that there is no frost on this IC's pins to prevent malfunction by short-circuit. Also attention should be paid in using on environment, which is easy to dew for the same reason. • 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 and all disputes arising out of or in connection with any infringement of the products including this IC upon patents owned by a third party. 8 HIGH-ACCURACY DIGITAL TEMPERATURE SENSOR WITH THERMOSTAT FUNCTION Rev.1.1_00 S-5852A Series Characteristics (Typical Data) 1.
