Introduction

The MAX6376XR23+T is an advanced supervisor IC that combines a watchdog timer and system reset with a highly integrated solution. It is designed to ensure correct power-on sequencing and system reliability in a wide range of applications, such as servers, high-end computers, televisions and set-top boxes, personal electronics, and industrial, transport, and communication systems. This device is an excellent choice for customers who require highly reliable power-on and system reset functions in order to provide a more secure system environment.

PMIC - Supervisors

PMIC – Supervisors are devices that are essential for system reliability and safety. They provide intelligent and real-time monitoring for system integrity and operation. With the MAX6376XR23+T application field and working principle, it is able to guarantee the performance and reliability of the whole system as it monitors the power supply voltage, temperature and correct sequence of voltage rails. The MAX6376XR23+T has multiple operating modes which can be configured and adjusted through external components. It monitors the power supply voltage and system temperature with the help of low-output voltage detectors and high-temperature detector, respectively. The main operating power supply voltage can also be monitored with an additional output voltage detector. Upon detection of any failure in any of these parameters, the MAX6376XR23+T generates a reset signal to automatically reboot the system.When the power supply voltage, temperature and correctly programmed timers meet their respective requirements, the reset signal is cancelled. The reset signal generated by the MAX6376XR23+T is applied to a fuse, an external MOSFET switch and/or the power-on reset (POR) circuit, depending on the application requirements. It has also two programmable outputs to indicate whether the system is ‘ON’ or ‘OFF’, with both outputs operating in an open-drain configuration.

The Key Features of MAX6376XR23+T

The MAX6376XR23+T offers a number of features that make it an ideal solution for applications that require accurate and reliable power-on sequencing and system reset. • It has an internal chip fuse that can be used to restart the device according to application requirements. • The high-temperature detector monitors the system temperature and triggers a reset output if it exceeds its programmed threshold. • Its low-output voltage detectors monitor voltage rails to prevent supply voltage breakdown during system startup and detect under-voltage conditions. • It has two programmable outputs that indicate whether the system is ‘ON’ or ‘OFF’. • It has a watchdog timer with adjustable time-out period that can be used to monitor the system performance and timing.• Its low stand-by power consumption and minimal offset voltage drift ensure long cycle-to-cycle stability and reliable operation over a wide temperature range. • Its dual-voltage power supply design provides superior power supply flexibility and allows the device to function in the most stringent application environments. • An intelligent system-rebuild sequence is implemented if a reset is triggered, preventing unwanted system deactivation.

Conclusion

The MAX6376XR23+T is an ideal device for applications that require reliable system reset, power-on sequencing, and protection against under-voltage and over-temperature conditions. Its combination of versatile features, low power consumption, and accuracy over a wide temperature range makes it a highly reliable and cost-effective choice for a variety of applications.
