Its wide operating voltage range of 2.4 to 8.0 V makes it suitable for a number of applications requiring accurate temperature control, such as electronic thermostats for climate control, refrigerators, and industrial process controls. The device is in the “on” state when the control pin is pulled to a logic high level. A typical application is to make a digital representation of temperature with an A/D converter, or to make a thermal detector with a comparator. Note: Both GND pins must connect to GND TK11034 VCC 01 S VOUT GND NC GND VCONT The TK11034 has a compensation pin for a 0.1 µF capacitor that ensures stability over the IC's operating temperature range. The TK11034 is available in a miniature SOT-23L surface mount package. BLOCK DIAGRAM VCC ORDERING INFORMATION VCC VCONT TK11034M Tape/Reel Code ON/OFF CIRCUIT TEMPERATURE DETECTION CIRCUIT + VO...
