The AS1912V-T is a commonly used PMIC - Supervisors for automotive, industrial and communications applications. It is a highly integrated, cost-effective and reliable power system supervisor IC. The AS1912V-T combines self-test, system reset, and watchdog timer functionality into one package. It is designed to help system designers manage their power systems more effectively and increase their system’s reliability, resulting in a solution that increases the customer’s time-to-market.

Overview

The AS1912V-T is a single-package solution combining 3 primary functions in a single package: system reset, self-test, and watchdog timer. The AS1912V-T is designed to provide system designers with more protection and reliability in their power designs. The AS1912V-T provides the user with the ability to configure their power system design to their system’s needs in order to maximize performance and protect their system from power system faults. The AS1912V-T also includes features such as: power-on reset, under-voltage and over-voltage reset, and watchdog timer functions.

Application Field

The AS1912V-T is designed for automotive, industrial and communications applications. As such, it is suitable for a wide range of applications such as automotive infotainment systems, security systems, industrial automation, wireless communications, mobile devices and other related applications. The features of the AS1912V-T includes an adjustable reset threshold, a programmable reset delay and adjustable tolerance of input voltage variation. All these features provide the user with the ability to customize their power system to their specific system needs.

Working Principle

The AS1912V-T works by monitoring both input and output voltages. When an output voltage falls below the preset threshold, a reset signal is triggered by the AS1912V-T. This reset signal will then reset the system, allowing it to reboot and continue operation. The AS1912V-TL also has a watchdog timer feature which tests the system at regular intervals. If the system fails to respond within the preset time, a reset is triggered, allowing the system to hopefully recover from any issue that caused the system to freeze. The AS1912V-T also has an adjustable reset delay, allowing the user to adjust the delay time to their desired needs.

Another critical aspect of the AS1912V-T is its ability to detect input voltage irregularities. This feature of the AS1912V-T allows it to detect when the input voltage drops below the preset threshold or rises above the preset threshold. When either of these events occur, the AS1912V-T will forcefully reset the system, protecting it from power system faults.

Conclusion

The AS1912V-T is a highly integrated and cost-effective PMIC - Supervisors for automotive, industrial and communications applications. This supervisor IC can provide a wide range of benefits to the user, from its power-on reset and watch dog timer features to its under-voltage and over-voltage reset capabilities. Additionally, the AS1912V-T provides protection from power system faults and allows user to customize their system design in order to maximize performance. As such, the AS1912V-T is an ideal choice for those seeking a reliable and cost-effective power system supervisor.
