The MAX6385XS24D4-T belongs to the PMIC - Supervisors category and is a voltage supervisors with programmable reset and watchdog functions. It offers multiple advantages for monitoring the function and condition of other circuits, such as relays, motors, and power converters. This supervisor is designed with a dual, nonretainable reset function that can be programmed to detect both overvoltage and undervoltage conditions.

The MAX6385XS24D4-T is highly reliable, with a wide operating temperature range, and a reset propagation delay that powers up reset outputs quickly. The supervisor is self-powered and uses a low-current current limiting circuit to optimize system accuracy and reliability. It monitors two independent supplies, making it a versatile support device for industrial as well as consumer applications.

Applications Areas

The MAX6385XS24D4-T can be used in a variety of applications where monitoring the voltage levels is a main function. These areas include:
• Automotive, aerospace and other industrial applications.
• Telecommunications and networking equipment.
• Automated testing systems.
• Battery backup / UPS systems.
• Power inverters, solar regulators, and battery chargers.

Working Principle

The MAX6385XS24D4-T works by monitoring two power supplies with different thresholds. When the voltage of either supply exceeds the threshold, an integrated logic circuit will activate the reset output. The reset output will remain active until the condition is cleared and both power supplies are at an acceptable voltage level. This dual-channel reset feature allows the supervisor to respond quickly to multiple power supply conditions.

The supervisor also features a watchdog timer to detect abnormal system conditions. When enabled, the watchdog timer will reset the system if it fails to be cycled within a user-specified time interval. This feature can be used to detect system lockups, oscillation failures, or other undesirable failures.

Benefits

The MAX6385XS24D4-T offers multiple benefits when used to monitor the function and condition of other circuits. It provides accurate monitoring of two independent supplies and can be programmed to detect both overvoltage and undervoltage conditions. It is also highly reliable, with a wide operating temperature range and a reset propagation delay that powers up reset outputs quickly. Additionally, it is self-powered and uses a low-current current limiting circuit to optimize system accuracy and reliability.

Conclusion

The MAX6385XS24D4-T is a versatile, high-accuracy voltage supervisor that can be used in a variety of applications. It is designed to quickly respond to multiple power supply conditions and its watchdog timer feature helps to detect system lockups, oscillation failures, and other undesirable failures. Its innovative design makes it an ideal choice for automotive, aerospace, and industrial applications, as well as automated testing systems, battery backup/UPS systems, and power inverters.
