Ultra Small Analog Output Temperature Sensor with Alarm Output Pin
■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 3.5μA (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.

■ OPERATIONAL EXPLANATION
A small ratio of the analog output (VAOUT) of the XC3101 series is fed back to one input of the error amplifier via the voltage
divider formed by the R1x and R1y resistances. The error amplifier compares this feedback voltage with the voltage of the
internal temperature sensor that is connected to its other input, and the resulting output signal from the error amplifier drives
the Pch-MOS transistor that is connected between the VDD and VAOUT pins. This cycle of events stabilizes the VAOUT voltage
via negative feedback. The internal temperature sensor is controlled so that the voltage changes on a fixed temperature
slope with respect to changes of ambient temperature, and a voltage with a fixed temperature slope is thereby output from
the analog output (VAOUT).
By comparing the internal voltage reference –which has a small temperature slope- with the voltage, divided by R1x and
R1y, of the analog output (VAOUT) –which has a fixed temperature slope-, the comparator outputs a voltage that turns the
Nch-MOS transistor ON and OFF. Since this Nch-MOS transistor is connected to the VDOUT pin, we actually control the alarm
output voltage (VDOUT).
XC3101 Series
<Analog output>
Due to its fixed temperature slope over the temperature range of -40°C to 100°C, the analog output (VAOUT) of the
XC3101 series outputs a voltage that varies linearly with changes in ambient temperature. For the XC3101A type, whose
temperature slope is -11.77mV/°C (typical), the analog output voltage at Ta=25°C is 1.6V (typical). The temperature
accuracy by means of the analog output voltage is ±3.5°C.
<Alarm output>
The alarm output (VDOUT) of the XC3101 series holds the alarm output voltage at Low (VSS potential) when the ambient
temperature rises and the alarm temperature -a threshold set inside the IC- is exceeded. When the ambient temperature
drops below the alarm temperature by an amount that is bigger than the hysteresis width, the alarm output voltage goes
High (pull-up voltage). The alarm output pin is an Nch open drain output, and thus when using alarm output, connect a
pull-up resistor to pull the voltage up to the desired voltage. If not using alarm output, pull the alarm output pin down to the
VSS potential.
<Input/output capacitor>
To stabilize the operation of the XC3101 series, connect a 0.1μF or higher output capacitor (CL) between the VAOUT and VSS
pins. To stabilize the input power supply, connect a 0.1μF or higher input capacitor (CIN).

■ NOTES ON USE
1. Please use this IC within the stated maximum ratings. For temporary, transitional voltage drop or voltage rising
phenomenon, the IC is liable to malfunction should the ratings be exceeded.
2. When the wiring impedance is high, noise wraparound due to the output current may cause analog output or alarm
output operation to become unstable. Sufficiently strengthen the VDD and GND wiring.
3. The input capacitor CIN and the output capacitor CL should be placed to the as close as possible with a shorter wiring.
4. Do not use the XC3101 series with a voltage lower than VSS applied to the alarm output pin (VDOUT).
5. If VIN changes sharply, the analog output will also change sharply, and malfunctioning of the alarm output may result. In
this event, adjust the slew-rate to less than 2 V/ms by increasing the input capacitor (CIN) or other means.
6. Torex places an importance on improving our products and its reliability.
However, by any possibility, we would request user fail-safe design and post-aging treatment on system or equipment.
