TC622VPA传感器变送器的温度传感器-温控器-固态规格书PDF中文资料

TC622VPA属于传感器变送器的温度传感器-温控器-固态。由美国微芯科技公司制造生产的TC622VPA温度传感器 - 温控器 - 固态固态温控器产品是基于半导体的温度检测器件，具有双态输出，当测量温度超出固定界限或定义范围时，输出状态会相应地发生变化。此类产品包括提供预设温度阈值和可编程/可配置阈值的器件。

GENERAL DESCRIPTION

The TC622 and TC624 are programmable solid state temperature switches designed to replace mechanical switches in sensing and control applications. Both devices integrate the temperature sensor along with a voltage reference and all required detector circuitry to form a stand-alone temperature switch. The desired temperature set point is set by the user with a single external resistor.

Ambient temperature is sensed and compared to the programmed setpoint. The OUT and OUT outputs are driven to their active state when the measured temperature exceeds the programmed setpoint.

The TC622 has a power supply voltage range of 4.5V to 18.0V while the TC624 operates over a power supply range of 2.7V to 4.5V. Both devices are usable over a temperature range of – 40°C to +125°C (TC622Vxx, TC624Vxx). Both devices feature low supply current making them suitable for many portable applications.

Eight-pin through-hole and surface mount packages are available. The TC622 is also offered in a 5-pin TO-220 package.
