01S

TEMPERATURE SENSOR IC

FEATURES

■ Linear Output Voltage 10 mV/°C Output

■ Active High On/Off Control

■ 2.4 to 8.0 V Supply Range

■ Miniature Package (SOT-23L)

■ Minimum External Parts Count

■ Low Power Consumption

DESCRIPTION

The TK11034 is a temperature sensor IC with a linear output of 10 mV/°C over the range of -30 to + 105 °C. 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.

The TK11034 has a compensation pin for a 0.1 µF capacitor that ensures stability over the IC's operating temperature range.

APPLICATIONS

■ Home and Industrial Thermostats

■ Automotive Climate Control

■ Battery Charger Temperature Monitor

■ Notebook Computer Temperature Monitor

■ Electronic Thermometers

■ Fish Finder Water Temperature

■ Industrial Process Controllers

■ Home Appliance Temperature Control
