Power management integrated circuit (PMIC) has a wide range of applications in regulating voltage and current in many different systems or devices, especially those involving microcontrollers and embedded systems. The MAX6385XS31D6-T is a PMIC - Supervisors, comprising of a set of features that helps in actively monitoring power supply voltages, system and device temperatures, and providing protection in low-voltage environments. In this article, we take an in-depth look into the application fields and working principle of the MAX6385XS31D6-T and its performance characteristics.

Application Fields for the MAX6385XS31D6-T

The MAX6385XS31D6-T can be used across a variety of devices and systems, performing as a digital supervisor to monitor voltage levels. The device is popularly used in switching power supplies, regulators, and linear designs, with favorable performance characteristics across different power supply currents. Due to its low quiescent current, it can also be implemented in low power systems such as remote management applications, connected devices, and embedded systems.

The supervisor is generally designed to operate in 1.7V - 5.5V input voltaes and 5.5V - 40V output voltages, with a supply current of about 10μA. Also, the device is rated for an operating temperature of -40 to 125 degrees Celsius which makes it suitable for use in a variety of environments and conditions.

Working Principle of the MAX6385XS31D6-T

The MAX6385XS31D6-T is made up of four main functional blocks: voltage supervisor, watchdog timer, overvoltage monitor, and temperature monitor. The device works by actively monitoring the power supply voltage levels, thereby detecting outages and preventing system malfunctions or unexpected shutdowns.

The voltage supervisor is responsible for comparing the power supply voltage to the device\'s supervisor trip point. Whenever the voltage drops below the trip point, an adjustable delay is initiated before triggering the system reset signal. The device also has a window watchdog timer that generates the system reset signal if the device fails to receive an active input within the configured timeout interval.

In addition to the voltage supervisor, the MAX6385XS31D6-T also has an overvoltage monitor to detect power supply levels that are above a preset reference point. Whenever the overvoltage condition is met, the device will immediately generate the system reset signal to protect the system from masking or being damaged.

Lastly, the MAX6385XS31D6-T also has a temperature monitor that monitors the actual device temperature and compares it to the setup trip point. When the temperature exceeds the reference level, the device will immediately generate the system reset signal to prevent any further issues.

Performance Characteristics

The MAX6385XS31D6-T provides superior performance when compared to many other supervisor solutions. One notable feature is the low quiescent current, with 10μA in normal operation and 35μA in reset operation. The device also has an adjustable reset delay of up to 140 seconds, and a maximum reset pulse width of 200 milliseconds.

Moreover, the MAX6385XS31D6-T provides better overvoltage protection, with a maximum overvoltage protection of 50V, and a maximum undervoltage detection of 1.8V. The device also has an open-drain active low reset output, with a logic low varying between 0.4V and 0.8V. Additionally, the device is capable of powering on and off multiple load domains.

In conclusion, the MAX6385XS31D6-T is a versatile and reliable PMIC - Supervisors that operates between 1.7V to 5.5V, and 5.5V to 40V. It provides superior performance in active monitoring of power supply levels, system and device temperatures, and providing protection from outages. It is a suitable solution for low power systems such as remote management applications and embedded systems.
