HIGH-ACCURACY DIGITAL TEMPERATURE SENSOR
WITH THERMOSTAT FUNCTION
The S-5852A Series is a high-accuracy digital temperature sensor with thermostat function, which operates in 1.7 V to 3.6 V
voltage ranges. The S-5852A Series interfaces with exteriors via I2C-bus and operates at 1.0 MHz maximum. The
temperature detection signal is output by using the thermostat function which can be set by the I2C-bus. Moreover, a
substantial reduction in current consumption may be achieved by using the shutdown mode which can be set by the I2C-bus.
The operation of the S-5852A Series is explained in the user's manual. Contact our sales office for more information.
Caution This product is intended to use in general electronic devices such as consumer electronics, office
equipment, and communications devices. Before using the product in medical equipment or automobile
equipment including car audio, keyless entry and engine control unit, contact to SII is indispensable.
