DatasheeDatasheett Temperature Sensor ICs Low Current Thermostat Output BDJxxx0HFV Series General Description Key Specifications BDJxxx0HFV series is a thermostat output temperature Power Supply Voltage Range: 2.4V to 5.5V sensor IC with built-in temperature detection element, Supply Current: constant current circuit, and a high-accuracy reference Normal Function mode 7.5A (Typ) voltage source in one chip. Temperature detection can Power Down mode 0.3A (Typ) be realized at 2.5C accuracy without the need for a High Accuracy Thermostat: complicated design. It is best suited for portable 2.5C (Max) Ta=55C to 80C equipment of micro- and low-current, power down Sensing Temperature Hysteresis: 10.0C (Typ) function, and battery drive. It is possible to use it for a High Accuracy Analog Output: wide range of applications such as heat detection and 2.5C (Max) Ta=-30C to +100C temperature monitors because it provides an analog Analog Output Temperature Sensitivity: output in addition to the thermostat power output. -8.2 mV/C (Typ) BDJxxx0HFV series has 5 products at 55C, 60C, Operating Temperature Range: -30C to +100C 65C, 70C, and 80C detection temperature. Features Package W (Typ) x D (Typ) x H (Max) Detection Temperature lineup at 55C, 60C, 65C, 70C, and 80C (5 products) Built-in power down control function.
