G708 台湾致新代理商 GMT 温度传感器和风扇控制器和风扇驱动器系列 热敏开关
Resistor-Programmable SOT Temperature Switches

General Description
The  G708  are  fully  integrated,  resistor  programmable  temperature  switches  with  thresholds  set  by  an  exter-nal resistor. They require only one external resistor to set  the  temperature  threshold  within  a  wide  0°C  to  +125°C  temperature  range.  The  G708  provides  an  open-drain, active low output. These switches operate with  a  +2.7V  to  +5.5V  single  supply  while  providing  a  temperature  threshold  accuracy  of  ±0.5°C  (TYP)  or  ±3.5°C  (MAX)  or  ±3°C  (60°C  to  +100°C).  They  typi-cally  consume  33μA  supply  current.  Hysteresis  is  pin  selectable to 10°C or 30°C. The G708 are available in 5-pin SOT-23 and TDFN2X2-8 packages.
