1. Introduction to MIC826ZYMT-TR

MIC826ZYMT-TR is an advanced and high performance PMIC (power management integrated circuit) supervisors from Microchip Technology. It is designed to provide power monitoring, over-voltage and over-current protection for many applications. This device provides excellent protection through a two-stage over-current control which reacts quickly to detect current faults and shut down the supply to prevent damage to any other components downstream. It has several options for fault response depending on the application, including latching or cycling off with a small delay. Its latch-off feature can be enabled or disabled for each supply output. Also, the device has an 86 dB dynamic range to allow accurate detection of fault current even in noisy environments. It also has an adjustable reference threshold that allows the device to be optimized for different applications. The MIC826ZYMT-TR is available in an SOT-23-5 package and is offered in three versions: high temperature (H), low current (L) and standard temperature (T).

2. Application Field of MIC826ZYMT-TR

The MIC826ZYMT-TR PMIC supervisor is a highly-integrated power monitoring and protection device designed for a variety of industrial and consumer applications. It is suitable for automotive and industrial systems, telecom base stations, medical systems, motor control, solar and battery-powered systems and many other applications. This device can provide supply power monitoring and protection functions for both DC and AC systems. It is an ideal choice for grid connected applications such as microgrids, inverters or other applications in an industrial setting. It can also be used for distributed energy storage systems, such as Li-ion batteries.

3. Working Principle of the MIC826ZYMT-TR

The MIC826ZYMT-TR PMIC supervisor is a low-cost, highly integrated device that combines over-voltage, under-voltage, overtemperature and over-current protection into one IC. The device includes a comparator that monitors output voltages and has configurable thresholds and hysteresis. It also includes a current sense amplifier with adjustable gain that measures the output current and has configurable thresholds and hysteresis.If the output voltage or current is above the adjustable thresholds, the device will trip and the power supply will be shut off. The device also allows for extremely fast response times with over-current protection and over-voltage protection. The supervisory delay on the MIC826ZYMT-TR can be adjusted from 0.2 s to 200 s, depending on the application.In case of a fault, the user can configure the device to either latch off or cycle off with a small delay. The device also has a temperature-sensing input, which can be used to monitor temperature and provide over-temperature protection.

4. Conclusion

The MIC826ZYMT-TR PMIC supervisors is a reliable power monitoring and protection IC that provides highly integrated and effective protection against both over-voltage and over-current conditions. It is an ideal device for a wide range of applications in industrial and consumer markets. This device is an excellent choice for many industrial and consumer applications, such as automotive, telecom base stations, medical, motor control, and distributed energy storage systems. It offers fast fault detection, adjustable thresholds and hysteresis, and configurable latching or cycling off with a small delay.
