XC31B
Series
CMOS Temperature Sensor
ETR0901_001
■GENERAL
DESCRIPTION
The XC31B series are ultra small CMOS temperature sensor ICs. As a bandgap type temperature sensor is built-into the
XC31B, linearity, in comparison to thermistor type temperature sensors, is much better.
The operating temperature range of the series is from -30℃ to +80℃. The XC31B comes in a mini molded SOT-25 and
USP-6B packages with a supply current of only 7μA
(@V
OUT
=2.0V) and as such, is suitable for use with various portable devices. Output voltage is selectable in 100mV
increments within a range of 2.0V to 6.0V (at 25℃).

*The dissipation pad for the USP-6B
package should be solder-plated in
recommended mount pattern and metal
masking so as to enhance mounting
strength and heat release.
If the pad needs to be connected to other
pins, it should be connected to the V
SS
pin.
