Power management integrated circuits (PMICs) are becoming increasingly popular, as they provide the design engineer with a convenient way to manage their energy requirements. Supervisors are an important part of PMICs, as they offer advanced protection against power interruptions and power cycling events. The MAX6388XS28D4-T is a supervisor device that bring comprehensive protection to a wide variety of systems.

Overview of MAX6388XS28D4-T Supervisors

The MAX6388XS28D4-T is a low-power supervisor from Maxim Integrated. It is designed to provide a comprehensive power reset, voltage monitoring, and fault detection solution for a wide variety of systems. It has integrated power-up and power-down circuitry, and provides adjustable reset time delays and voltage thresholds. The MAX6388XS28D4-T can be used to protect against excessive currents, undervoltage conditions, overvoltage conditions, and power cycling events.

Application Field of MAX6388XS28D4-T

The MAX6388XS28D4-T is suitable for applications where stringent power management is required. It is ideal for embedded systems, consumer electronics, automotive, factory automation, and medical electronics applications. This device is also well-suited for use in harsh environments where robust protection of the system is critical.

Features of MAX6388XS28D4-T

The MAX6388XS28D4-T offers a range of features designed to provide an advanced and reliable reset and power monitoring solution. It supports supply voltages from 1.4 to 10V, reset activity at 1.4V, and can drive outputs up to 10mA. It offers adjustable active-high and active-low thresholds and different reset time delays. It also features an external voltage monitor and an internal precision voltage reference. The reset and power monitoring functions of the MAX6388XS28D4-T are resilient to fault conditions, such as overvoltage and undervoltage conditions.

Working Principle of MAX6388XS28D4-T

The MAX6388XS28D4-T is a dual-channel supervisor with active-high and active-low outputs. It has an integrated voltage reference with a voltage threshold of 0.5V or 1V, depending on the mode settings. The active-high output signals when the input voltage exceeds the threshold, and the active-low output signals when the input voltage drops below the threshold. The MAX6388XS28D4-T features an adjustable reset time delay, which allows the user to configure the length of time before the reset output is asserted. The reset output is asserted for a period of time determined by the reset-delay setting.

The MAX6388XS28D4-T has an external voltage monitoring input and indicates when the voltage is above or below the threshold. It also features an integrated rising/falling delay, which allows a controlled response to an overvoltage or undervoltage condition. When the MAX6388XS28D4-T detects an overvoltage or undervoltage condition, it can either reset the system or issue a reset signal. The user can configure the behavior of the device to suit their individual needs.

Conclusion

The MAX6388XS28D4-T is an advanced supervisor device that provides comprehensive power management, reset and fault detection solutions. It is ideal for applications where tight control of the power budget is critical, and it offers adjustable thresholds and reset times to allow users to meet their specific requirements. The MAX6388XS28D4-T features an integrated voltage reference and an external voltage monitor, allowing it to offer reliable protection against overvoltage, undervoltage and power cycling events.
