LM27CIM5-1HJ

Introduction

Temperature sensors, thermostats, and solid state devices have been used in various industries for many years. Generally, these are used for monitoring and controlling the temperature of a certain environment or product. The LM27CIM5-1HJ is a highly versatile, solid-state temperature sensing device specifically designed for a variety of applications.

Application Field

The LM27CIM5-1HJ is commonly used in consumer goods, automotive, and industrial applications. It is capable of measuring temperatures from -40°C to +125°C (-40°F to +257°F). This device is ideal for applications in which precise control of temperature is required, such as in thermostats, ovens, and refrigerators. It can also be used in motors, engines, and other temperature-sensitive machinery.

The device is also used in various testing and measurement applications. It can be used to measure the temperature of chips in personal computers, or to measure temperatures in any type of electronic device. It can be used to monitor the temperature of a room or environment, or to monitor the temperature of industrial processes.

Working Principle

The LM27CIM5-1HJ features an analog output voltage proportional to temperature, which is determined by an internal programmable reference point. It is based on a thermistor principle; it contains an NTC thermistor and a Schottky diode, as well as an integrated circuit and a voltage regulator. The thermistor is used to measure temperature, while the Schottky diode is used to provide a stable reference voltage for the IC.

The internal circuitry of the device will adjust the output voltage according to the ambient temperature. The user can easily program the reference point or set point according to their desired temperature. The device will then automatically adjust the output voltage in order to maintain the desired temperature.
