Torex Announces Small Analog Temperature Sensor with Low Quiescent Current
Torex Semiconductor Ltd. has developed an ultra-small (1.2 x 0.9 x 0.4mm) analog temperature sensor with low quiescent current and alarm temperature detection function. The XC3101 series of analog temperature sensors use the ultra-small USPN-4 package (1.2 x 0.9 x h0.4mm), achieve low quiescent currents, and include an alarm temperature detection function. The output combines an analog output and an N-ch open drain alarm output in an ultra-small size.
The operating voltage range is 2.7 to 5.5V and can be driven by a lithium ion battery or 5V line. The quiescent current is a low 3.5µA (TYP.), and these sensors are well suited for temperature detection in battery devices. The analog output provides a high-accuracy analog voltage (1.600V @ 25℃) in the range -40 to 10°C. The analog output temperature coefficient is -11.77mV/℃. The alarm temperature is set to 70°C (±4.5°C) and the hysteresis is set to 5°C.
In addition to the ultra-small USPN-4 package, the standard-type SSOT-24 is also used. This environmentally friendly product complies with the EU RoHS Directive and is Pb free.
