Introduction to Supervisors

Supervisors are essential components for almost any embedded system as they help to prevent costly and damaging system failures. These supervisors are also commonly referred to as power management integrated circuit (PMIC) supervisors. PMIC supervisors are integrated circuits that are specifically designed to monitor and protect an embedded system\'s power supply. PMIC supervisors provide a variety of power management functions in one device, including power-on reset, voltage monitoring and voltage regulation.

Supervisors – The MAX8211MSA/PR-T

The MAX8211MSA/PR-T is a low-power, high-accuracy power management supervisor from Maxim Integrated. It is a two-input supervisor device featuring 0.5% accuracy across the full temperature range of -40°C to +125°C and low quiescent current of 200nA. With its wide input range from 2V to 28V, the MAX8211MSA/PR-T is an ideal solution for main, reset and power supply on applications such as telecom systems and embedded systems.

Application Field of MAX8211MSA/PR-T

The MAX8211MSA/PR-T is designed for use in a wide range of applications, such as telecom systems, embedded systems and industrial, transportation, and medical systems which require reliable power management. It is a two-input supervisor device with two separate power monitoring and reset functions, offering low power consumption and high accuracy across the full temperature range of -40°C to +125°C. The MAX8211MSA/PR-T is also ideal for use in space-constrained systems, such as power supplies, battery-operated systems, and microprocessors.

Working Principle of MAX8211MSA/PR-T

The MAX8211MSA/PR-T is designed to detect and respond to abnormal power supply events in order to protect the embedded system from unexpected power-related damage. It contains two independent power monitoring and reset functions, each with its own active-low reset output. The power monitoring function is designed to monitor the power supply voltage and provide an active-low reset when the voltage drops below a user-defined threshold. The second function is the reset function, which provides an active-low reset when the reset input remains active for a certain amount of time.The MAX8211MSA/PR-T also offers several user-configurable features, such as reset input reset delay position, reset enable/disable and reset output reset delay time. In addition, the MAX8211MSA/PR-T also features an adjustable reset watchdog timer that monitors the reset input circuitry and provides a reset when the reset input remains active for an extended period of time. All of these features work together to ensure reliable and consistent power management for the embedded system.

Conclusion

The MAX8211MSA/PR-T is a versatile, low-power, high-accuracy power management supervisor from Maxim Integrated. It has a wide input voltage range from 2V to 28V and offers several user-configurable features such as reset input reset delay position, reset enable/disable, and reset output reset delay time. With its low quiescent current of 200nA and wide temperature range of -40°C to +125°C, the MAX8211MSA/PR-T is ideal for use in a variety of embedded systems, including telecom systems, industrial systems, and transportation, and medical systems. Its two independent power monitoring and reset functions, together with its adjustable reset watchdog timer, ensure reliable and consistent power management.
