<h3>AS1910S-T Application Field and Working Principle</h3><p>AS1910S-T is a voltage supervisors device belonging to PMIC &ndash; Supervisors group, which is widely used in professional home appliances, communication and industrial control system. A voltage supervisor is an interface device. It has three main functions, which are over-voltage protection，under-voltage protection and system reset. </p><h4>Application Fields</h4><p>AS1910S-T provides a low cost, high accurate and effective solution for equipment design, power supply system and power devices. It is widely used in professional home appliances, communication equipment, industrial control system and all other microprocessor-based application fields. The AS1910S-T product features high precision and excellent performances, it is easy to implement, and the application can be reduced significantly. Its chip core design has been proven and is safe, reliable and durable.</p><h4>Working Principles</h4><p>The AS1910S-T is designed to detect over-voltage and under-voltage problems and reset the microcontroller. The working principles of voltage supervision are based on the fact that a higher than expected voltage (over-voltage) or lower than expected voltage (under-voltage) results in incorrect system operation. The AS1910S-T can detect these voltage fluctuations and reset the system.</p><p>The AS1910S-T includes an internal power supply which provides power to the voltage supervisor to monitor the voltage. The voltage supervisor then compares the voltage level that it monitors to a preset threshold voltage. When it detects an over-voltage or an under-voltage, it sends a signal to reset the microcontroller.</p><p>The AS1910S-T integrates a long reset delay time (1 second) and a wide power supply range. It also integrated reset signal temperature compensation, so that regardless of temperature or voltage fluctuations, the AS1910S-T can alert the system to the over-voltage and under-voltage condition early enough to prevent damage to the system.</p><h4>Conclusion</h4><p>AS1910S-T is a voltage supervisors device belonging to PMIC &ndash; Supervisors group, which is widely used in professional home appliances, communication and industrial control system. The AS1910S-T product features high precision and excellent performances, it is easy to implement, and the application can be reduced significantly. In addition, the AS1910S-T also integrated reset signal temperature compensation, which ensures that regardless of temperature or voltage fluctuations, the AS1910S-T can alert the system to the over-voltage and under-voltage condition early enough to prevent damage to the system. </p>
