EMC2106-DZK-TR

Power management integrated circuits (PMICs) have become ubiquitous and are used in many modern systems to ensure efficient operation. Thermal management is one of the main functions of a PMIC, as it ensures the components and subsystems don’t exceed their optimal temperature range, reducing the likelihood of failures or emergency shutdowns. The EMC2106-DZK-TR is an example of a PMIC dedicated to thermal management. This article will discuss the application field and the working principle of this particular device.

The EMC2106-DZK-TR is designed for temperature control in low-profile, fanless applications. It is often found in servers and other mission-critical industrial equipment. It can also be used in consumer devices, such as set-top boxes, home theater systems, and gaming consoles. The device has a wide operating voltage range and features low static power consumption, good heat dissipating capability, and a thermal shutdown protection (TSP) feature.

The EMC2106-DZK-TR has two main components - a temperature sensor and a control circuit. The integrated temperature sensor is a negative temperature coefficient (NTC) thermistor which detects the ambient temperature. The control circuit is composed of an open-loop multiplier, an oscillator, and a temperature regulated switch. The oscillator turns the switch off and on, resulting in a voltage pulse that is applied to the multiplier. The output of the multiplier is then used to control the fan\'s speed.

The device is designed to detect temperature changes and adjust the fan speed accordingly. It can detect a range of different temperatures, from 16 degrees Celsius to 125 degrees Celsius. The control circuit uses the open-loop voltage signal from the thermistor to adjust the frequency of the oscillator and thus adjust the fan speed. When the temperature rises above a certain threshold, the fan speed increases proportionally. Conversely, if the temperature falls below the set threshold, the fan speed decreases.

The EMC2106-DZK-TR operates in an open- loop mode. It does not rely on feedback control or the use of a separate temperature sensor. The control circuit uses the integrated thermistor to detect temperature changes and then adjusts the fan speed accordingly. Additionally, the device has an integrated thermal shutdown protection (TSP) feature to prevent any catastrophic events occurring due to excessive temperature.

The EMC2106-DZK-TR is a reliable, cost-effective thermal management solution for applications which require low-profile, fanless designs. The device can detect temperature changes with ease and make the necessary adjustments to the fan speed without the need for a separate temperature sensor. Additionally, its integrated TSP feature ensures its reliable performance in extreme temperatures. For these reasons, the EMC2106-DZK-TR can be found in various mission-critical industrial equipment and consumer electronics.
