Power management integrated circuits (PMICs) are devices which combine multiple voltage regulators and/or power switching circuits into one integrated circuit package. A PMIC can be used to power many different applications, from simple to complex. Supervisors, such as the MAX6361LUT29+T, are a type of PMIC which are used to monitor and protect circuits from over- and undervoltage conditions. They are typically used in automotive, medical, industrial, and various other sensitive applications in order to ensure that the power levels remain within specific limits. This article will discuss the MAX6361LUT29+T supervisor in detail and explain its application field and working principle.

Application Field

The MAX6361LUT29+T supervisor is a cost-effective power-supply supervisor designed to monitor, detect, and protect circuits from overvoltage and undervoltage conditions. This supervisor is ideal for use in applications where voltage regulation and accuracy are paramount, including automotive, medical equipment, and industrial electronics. It is also well suited for use in regulated supplies, especially those requiring high accuracy sloped tracking of inputs and/or outputs. The MAX6361LUT29+T also has a wide operating temperature range of -40°C to +125°C, making it suitable for use in extreme environmental conditions.

This supervisor features two power-good status outputs, providing controlled reset signals for use in systems such as microprocessors, ASSPs, and DSPs. A Voltage Monitor Adjustment pin is also provided, allowing users to adjust the trip point of the supervisor. It also includes other features such as adjustable power-good delay, programmable hysteresis, and open-drain/push-pull outputs.

Working Principle

The MAX6361LUT29+T Supervisor is used to monitor the power levels of a system. It consists of an operational amplifier and comparator, which convert an input voltage into an output voltage. The amplifier is set up such that when the input voltage is below a certain threshold (the “threshold voltage”), the output voltage is high. When the input voltage is above the threshold voltage, the output voltage is low. The threshold voltage is typically user adjustable, allowing the user to set the voltage at which the supervisor will activate.

Once the supervisor has been activated, it triggers a reset signal which can be used to reset or shut down the system. The reset signal is typically generated in one of two ways: by pulling the reset pin to a low logic level, or by driving an open-drain output to a logic-low level. The supervisor also features a power-good status output which indicates when the system\'s power levels are being monitored properly. The power-good status can be used to power-up or power-down the system, depending on the status of the supervisor.

In addition to monitoring power levels, the MAX6361LUT29+T supervisor can also detect fault conditions such as undervoltage or overvoltage. If an undervoltage or overvoltage condition is detected, the supervisor will immediately activate the reset signal, shutting down the system until the condition is corrected. This ensures that the system remains safe and functional, and that no damage is caused by unregulated voltages.

Conclusion

The MAX6361LUT29+T is a cost-effective power-supply supervisor designed to monitor, detect, and protect circuits from over and undervoltage conditions. This supervisor is ideal for use in automotive, medical, and industrial applications, and is also suitable for use in regulated supplies requiring high accuracy sloped tracking of inputs and outputs. The supervisor features two power-good status outputs, adjustable power-good delay, programmable hysteresis, and open-drain/push-pull outputs. Finally, it can also detect undervoltage or overvoltage conditions, triggering a reset signal to shut down the system until the condition is corrected.
