XC3101

XC3101 Series Ultra Small Analog Output Temperature Sensor with Alarm Output Pin ETR0902-004 GENERAL DESCRIPTION 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 3.5 A (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. ■APPLICATIONS Base temperature monitoring on mobile devices Internal temperature monitoring on small electronic device Temperature monitoring (LCD, Module) Temperature control for FAN FEATURES Operating Voltage Ran...
