The TMP302DDRLR is a two-zone, temperature-sensing thermostat designed to provide highly accurate temperature control for a wide variety of applications. It is a solid-state, thermistor-based thermostat with an integrated COM-controlled switch. The device can be used to control two zones from the same temperature sensor with a range of 0°C to +125°C and a resolution of at least 0.25°C.

Application Field

The TMP302DDRLR thermostat can be applied in a number of applications, including medical equipment, HVAC controllers, automotive engine-control systems, home appliance controls, and industrial process and machine controls. This versatile thermostat can be used to provide temperature control in any application where accurate temperature control is necessary, including those that require multiple temperature zones.

Working Principle

The TMP302DDRLR is a two-zone thermostat that uses a thermistor-based temperature sensing element. The thermistor is a resistor whose resistance drops when the temperature of its environment increases. This resistance change is measured by the TMP302DDRLR and used to control its switching action. The device has two switches connected to a single COM port, allowing it to control two zones of temperature independently.

The device also features automatic self-calibration, which can maintain high accuracy over a wide temperature range, as well as an adjustable temperature hysteresis. The thermostat is preset with a set range of temperatures, but the user can easily reprogram the device to operate within a different temperature range. The adjustable hysteresis ensures that the device does not continuously switch back and forth, but rather maintains a steady temperature level within a certain range.

The TMP302DDLR also features a fail-safe operation in the event of a power loss. In this case, the device will switch to a preset temperature range that the power source can monitor. This allows for a quick return to normal operation in the event of a power failure.

The device is also designed to protect against false temperature sensing. A current limitation feature ensures that it will not malfunction due to an incorrect reading, avoiding any potential damage to the device or connected equipment. In addition, it features over-current protection and reverse voltage protection for added reliability.

Overall, the TMP302DDRLR is a versatile two-zone, temperature-sensing thermostat designed to provide highly accurate temperature control for a range of applications. Its flexible design makes it ideal for any application where temperature control is necessary and its robust features help ensure reliable and consistent performance.
