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 USP-6B packages with a supply current of only 7 A (@VOUT=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 ). to +80 . The XC31B comes in a mini molded SOT-25 and

*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 VSS pin.

*4: Linearity margin error (TL) is calculated as follows:
emax TL= Tse Ta
where emax = maximum error. The maximum error is the maximum difference between the actual measured value and the value on an approximated straight line.

TYPICAL APPLICATION CIRCUIT
NOTE ON USE
1. When the load capacitance CL is too large, oscillation may occur on the output signal. 2. Output signal overshoot will occur when the power (VIN) is switched on or when the power drastically fluctuates. The chip enable (CE) function is effective for helping to avoid overshoot and also in saving consumption current.
