Low Current Consumption Thermostat Output Temperature Sensor ICs - BDJ0550HFV

BDJxxx0HFV series is a thermostat output temperature sensor IC with built-in temperature detection element, constant current circuit, and a high-accuracy reference voltage source in one chip. Temperature detection can be realized at ±2.5°C accuracy without the need for a complicated design. It is best suited for portable equipment of micro- and low-current, power down function, and battery drive. It is possible to use it for a wide range of applications such as heat detection and temperature monitors because it provides an analog output in addition to the thermostat power output. BDJxxx0HFV series has 5 products at 55°C, 60°C, 65°C, 70°C, and 80°C detection temperature.
