PMIC, or power management integrated circuits, are specialized ICs designed to help manage power aboard an electronics device. PMICs are often found in consumer-grade products such as smartphones, where they help conserve battery life and ensure that all the device functions properly. One type of PMIC, known as Supervisors, are designed to monitor system health and voltages, protecting the device from damage due to faults or power issues.

The MAX16008TP+T Supervisors are one of the newer PMICs in the market, offering an impressive range of features that makes them ideal for a range of applications. In this article, we\'ll take a closer look at the MAX16008TP+T to explore its application field, discuss its features, and explain its working principle.

Applications

The MAX16008TP+T is designed for use in industrial, automotive, and consumer applications. The Supervisors come in an industry-standard 3mm x 3mm 16-pin MAX package, making them an ideal choice for small-form-factor designs, such as those found in motor control, wearables, and internet of things (IoT) products. The supervisors are also able to provide power restart protection in automotive designs, such as those used in computers, navigation systems, and other in-vehicle applications.

The MAX16008TP+T is a particularly useful PMIC because of its ability to monitor up to five power supply rails, making it well-suited for multi-rail designs. The Supervisors can also detect multiple fault conditions, such as over-voltage, under-voltage, and over-current, allowing them to protect the device from damage due to fault conditions. The MAX16008TP+T also has an integrated voltage-level translation circuit which simplifies the design of power systems that require voltage-level matching between components running at different voltages.

Features

The MAX16008TP+T supports up to five tracking channels and can hold a differential voltage of up to 36V. It offers adjustable tracking zoom of up to 10:1, adjustable output voltage setting range of 1.24V to 76V, and input voltage range of 2.375V to 36V. The supervisors also feature a built-in temperature sensor which provides accurate overtemperature shut-down protection.

The MAX16008TP+T offers undervoltage lockout protection, allowing it to detect when the specified output voltage has fallen below its lockout level. The supervisors also have an adjustable time delay, allowing users to set the time it takes for the output voltage to reach its set point after power-up and after any fault condition has been remedied. Lastly, the MAX16008TP+T features adjustable over-current protection, allowing for both constant-voltage and constant-current operation.

Working Principle

The MAX16008TP+T acts as a voltage supervisor, monitoring the output voltages of up to five power supply rails. The Supervisors are designed to detect multiple fault conditions, such as over-voltage, under-voltage, and over-current, and protect the device from damage due to those conditions. Upon detection of a fault, the supervisors will either shut down the power supplies or restart them, depending on the settings.

The Supervisors are designed with an integrated voltage-level translation circuit, which allows them to translate voltages between high-side and low-side rails, allowing for communication between components operating at different voltage levels. They also have an adjustable time delay, allowing the user to set the amount of time it takes for the output voltage to reach its set point after power-up and after any fault condition has been remedied.

The MAX16008TP+T also features adjustable over-current protection, allowing for operation as either a constant-voltage or a constant-current device. The feature also allows the user to set a current limit, ensuring that the device does not draw an excessive amount of current and become damaged or fail.

Conclusion

The MAX16008TP+T is a powerful and versatile PMIC designed for use in any application requiring reliable power supervision. The supervisors offer a range of features that make them ideal for industrial, automotive, and consumer applications, including their ability to monitor up to five power supply rails, their integrated voltage-level translation circuit, their adjustable time delay, and their adjustable over-current protection. With its impressive range of features, the MAX16008TP+T is a great choice for anyone looking to ensure reliable power management in their device.
