Torex Semiconductor Ltd has launched an analog temperature sensor with low quiescent current and alarm temperature detection function. The XC3101 series operates from 2.7每5.5V and uses the ultra-small USPN-4 package (1.2 x 0.9 x h0.4mm).


The XC3101 series uses the ultra-small USPN-4 package of 1.2 x 0.9 x 0.4mm.

The sensors are ideal for temperature detection in battery devices and can be driven by a lithium ion battery or 5V line. The quiescent current is a low 3.5?A (TYP.) and provides a high-accuracy analog voltage (1.6V at 25∼C) in the range -40∼C to 100∼C. The analog output temperature coefficient of the sensor is -11.77mV/∼C. The alarm temperature of the XC3101is set to 70∼C (㊣4.5∼C) and the hysteresis at 5∼C.

The RoHS-compliant and Pb-free temperature sensor comes in standard-type SSOT-24 packaging.
