MAX16091UK31BMA+T

PMIC - Supervisors

The MAX16091UK31BMA+T, manufactured by Maxim Integrated, is a system-power supervisor and precision monitor IC. This IC provides a complete power system solution by monitoring voltage levels and reporting any deviation from expected levels to the processor.

Application Field

The MAX16091UK31BMA+T is a very versatile supervisor IC. It is suitable for use in a variety of applications, including portable electronic devices, notebook PCs, desktop PCs, workstations, servers, automotive systems, and industrial systems. In any of these applications, it can be used to monitor a variety of voltage levels, including supply power, standby power, system reset and power-on reset signals.

Working Principle

The MAX16091UK31BMA+T integrates a variety of features that make it very suitable for power management. It includes two supply monitor comparators that can be used to detect the sudden voltage drop caused by brownouts and the presence of overvoltage conditions. When such a condition is detected, the IC can send a reset or interrupt signal to the processor. This can be used to prevent damage to the system caused by the sudden power disturbances.

The MAX16091UK31BMA+T also includes an adjustable reset timer, which is triggered by a low input voltage event or a timeout generated by the reset timer itself. This timer allows the system to reset itself after a predetermined amount of time, which helps to reduce the risk of further system damage caused by a power disturbance. This timer can be adjusted to different time periods. In addition, one of the comparators can be used to detect the power supply start-up voltage and generate a reset signal, which helps ensure that the system has enough power to startup correctly.

To further provide versatility, the MAX16091UK31BMA+T also includes a voltage-adjustment circuit, which can be used to transform a system’s input voltage into various supply voltages. This is beneficial as it eliminates the need for additional voltage regulators and allows for a single, simple power system design. The IC can also be used to write to an SPI or I2C interface to program user-defined threshold levels and to monitor multiple power supply lines.

Conclusion

The MAX16091UK31BMA+T is a comprehensive power system solution that provides precision monitoring and system control. Its versatile features make it ideal for a variety of applications. Its integrated voltage-adjustment circuit also allows for a simple and efficient power system design. As such, the MAX16091UK31BMA+T is an excellent choice for system power supervision.
