概要

The XC3101 series is a temperature sensor IC which features ultra small, low current consumption, and high-accurate detection.
It can provide both analog and alarm outputs. The alarm output configures N-channel open-drain. The device consists of a band-gap type temperature sensor, a voltage reference, a temperature setting tilt amplifier, a comparator, and various set resistors.
Alarm temperature is internally set at 70℃.
When the temperature exceeds a set point, the alarm output is maintained as "Low".
When the temperature drops a pre-set hysteresis width from the set point, the alarm output is released to "High". The hysteresis width is 5℃. ,An analog voltage output is provided in a high-accuracy which is guaranteed in the operating temperature range of -40℃ to 100℃. An external A/D can monitor the sensing temperature. ,The operating input voltage range is 2.7 to 5.5V. The small consumption current of 3.5μA (TYP.) is ideally suited for temperature detection for battery devices. The ultra small USPN-4 (1.2 x 0.9 x 0.4) package is available for the high-density board mounting in mobile device applications as well as an industry standard package SSOT-24.
