MAX16020PTEV+T

PMIC - Supervisors

MAX16020PTEV+T, the combination of a dual supervisor, power-on reset and voltage monitor from Maxim Integrated, is popular in designs for providing reliable power failure protection and other system defense solutions. It\'s suitable for many industrial, automotive and data management applications.

Application Field

The MAX16020PTEV+T has a wide range of applications. The dual supervisor provides a reset and a watch-dog timer using digital logic ICs, which makes it ideal for industrial controller, data communication and memory systems. The voltage monitor offers a comprehensive range of reset options and monitors that make it suitable for automotive applications, computer systems and high-end power management. And the power-on reset allows extra timings in combination with various other protection functions and provides over-voltage protection for systems.

Working Principle

The Dual Supervisor (DS) and voltage monitor from MAX16020PTEV+T are both timing devices that sense the power supply voltage and limit the time duration. They provide a reset signal to the system once the power supply voltage goes out of tolerance. The DS needs external components to extend the reset and set up the desired timing, while the voltage monitor uses a pre-programmed timing and has an ability to act as a voltage tolerance window.

The power-on reset (POR) is driven by the power supply voltage, so when the supply drops below the reset threshold, it asserts a reset to the system. This can be used to provide further protection during power-up or power-down transitions. It will reset the system directly once the power supply voltage falls outside the tolerance range.

Conclusion

Overall, MAX16020PTEV+T is an advanced PMIC for providing reliable protection for systems and industrial, automotive and data management applications. Its dual supervisor and voltage monitor timing functions, combined with the power-on reset, form a powerful combination that provides effective power failure protection.
