PMIC - Supervisors

The APX809-29SRG-7 is an automatic reset circuit with a capacity of 7.0 volts and a reset voltage threshold of 4.4 volts. It is part of a family of high precision circuits for the protection and monitoring of various types of systems. APX809-29SRG-7 has become a popular choice for automated reset circuits, as it provides reliable protection for a wide variety of applications.

The APX809-29SRG-7 supervisor circuit serves as an efficient safeguard for any system that requires a failsafe mechanism in the event of a power glitch or by a persistent drop in voltage in the system. It is available in Consumer, Industrial, and Automotive grades, making it suitable for many different environments.

This device offers a comprehensive range of features, such as dual-time reset and selectable active-low or active-high output configurations, as well as a wide range of reset and operating thresholds, ensuring the accuracy of the automatic reset operation. The device also works with a wide range of input voltages, and offers a wide operating temperature range.

The APX809-29SRG-7 is designed for a wide range of applications, including for notebooks, tablets, and wearable devices, as well as for automotive, industrial, avionics, and medical test and measurement equipment. Additionally, it is suitable for applications where low power consumption is critical, such as 3D clip-on or coin cell-type device power supplies.

The APX809-29SRG-7 can be used to detect a wide range of low or high power glitches or the presence of varying voltages in the system. It offers a robust monitoring solution for various systems and can be used to eliminate system power-related glitches. The time delay allows the system to respond in a more appropriate manner in case of a power glitch, thus ensuring safe shutdown and restart of the system.

When it is used as an automatic reset circuit, the APX809-29SRG-7 has two mechanisms. The first is a power-on reset, where the device monitors the voltage in the system and triggers a reset if the voltage drops below or exceeds the threshold voltage. The second mechanism is a watchdog timer, which monitors for certain conditions during operation and triggers a reset if the system does not respond correctly. When used in combination with an over-temp sensor, the APX809-29SRG-7 can be used as an auto-shutdown circuit, providing a supervisor that shuts down the power supply when the temperature exceeds a certain threshold.

The APX809-29SRG-7 is easy to use and set up, thanks to its minimal component count. It requires only an input capacitor and a reset output capacitor, which are easy to add onto existing systems. Its integrated power circuitry means it is self-contained, making it easy to integrate into existing designs and also minimizing power consumption. The integrated power supply also eliminates the need for additional power source for most of the operating conditions.

Overall, the APX809-29SRG-7 supervisor circuit offers an efficient monitoring and reset solution for a wide range of applications. Its accurate reset operation, low component count, and low power consumption make it an ideal choice for any system that requires reliable reset protection. Additionally, its various application-specific solutions such as a power-on reset and watchdog timer, mean it can be used in a variety of scenarios to provide superior protection against unforeseen power glitches.
