High-accuracy Digital Temperature Sensor with Thermostat Function S-5852A Series

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.
