Compact High Accuracy Temperature Sensor ICs ROHM Semiconductor Compact High Accuracy Temperature Sensor ICs are thermostat output temperature sensor ICs with a built-in temperature detection element, constant current circuit, and a high-accuracy reference voltage source in one chip. Temperature detection can be realized at ±2.5ºC accuracy without complicated design. ROHM Semiconductor Compact High Accuracy Temperature Sensor ICs are exceptional temperature sensor ICs for portable equipment with micro and low current, a power down function, and the battery drive. Because they provide analog output in addition to thermostat power output, these temperature sensors are ideal for a wide range of applications, such as heat detection and temperature monitors. The sensors are available with detection temperatures of 55ºC, 60ºC, 65ºC, 70ºC, and 80ºC.
