The TC652BEVUA is a solid-state temperature sensor and thermostat from Microchip Technology. This device is designed to provide accurate and reliable control of temperatures in the range of 10°C to 80°C with a resolution of 0.25°C. The device is capable of controlling temperatures with a resolution of 0.0625°C, which is the same resolution as an analog thermistor.

The working principle behind the TC652BEVUA is based on the sensing of temperatures via a thermistor network. A thermistor is basically a resistor whose resistance changes with temperature. The TC652BEVUA utilizes two such thermistors, one in the hot side and one in the cold side. The thermistors are connected to an adjustable reference voltage, and when a certain temperature is reached, the thermistors become resistors with equal values and the reference voltage is adjusted accordingly.

The TC652BEVUA is well suited for applications where tight control of temperature is required, such as in refrigeration systems and hot water boilers, or in ventilation systems for heating and air conditioning. In addition, the device is suitable for use in air purifiers, dehumidifiers, and other appliances which require precise temperature regulation. The device is also commonly used in industrial and medical applications, such as for controlling the temperature of cooling baths, ovens and incubators.

The TC652BEVUA is easy to install and requires minimal wiring and configuration. It is highly reliable and cost effective, making it ideal for use in a wide variety of applications. It can be configured to operate in either an open loop (direct control) or closed loop (proportional control) mode, allowing for precise temperature regulation and control.

In an open loop system, the TC652BEVUA is a simple two-point on/off thermostat. In this mode, the device responds to preset temperature points by switching power to the heated element when the set temperature is reached. This provides a simple yet reliable way of controlling a temperature-controlled system with just two temperature points.

In a closed loop system, the TC652BEVUA operates as a proportional controller, using a feedback loop to control the temperature. A feedback loop is used to monitor the temperature and modify the output of the proportional controller in order to maintain the desired temperature. The TC652BEVUA has a wide range of user-adjustable parameters, such as temperature hysteresis, control loop gain and other settings, allowing for fine-tuning of the temperature regulation.

The TC652BEVUA is a highly accurate and versatile temperature sensor and thermostat from Microchip Technology, with a wide range of applications in the industrial, medical and consumer markets. The device is easy to use, cost-effective, and provides reliable temperature control with a high resolution.
