The MIC809TUY-TR has become a popular choice for many system designs, due to its various protectioins and low-current consumption. This low-power form of supervisor is ideal for applications that require low-power protection, fallback triggers, or other features that are typically associated with less-costly power management systems. This article will discuss the application field of the MIC809TUY-TR as well as its working principle.

The MIC809TUY-TR was designed to provide system monitoring in battery-powered, low-power, portable electronic systems. Its supervisory functions include power-on reset (POR), brownout reset (BOR), and watchdog timer reset (WDR). Additionally, the MIC809TUY-TR features an adjustable reset threshold between 0.65 V and 3.3 V, allowing the user to easily select the most appropriate threshold for their system requirements. The MIC809TUY-TR also provides a power-fail output, which can be used to indicate to the processor when power has failed, reset has been initiated, or a brownout has occurred. Furthermore, the MIC809TUY-TR has both an active-low POR and an active-high POR reset signals to ensure a complete reset of the system.

The MIC809TUY-TR is compatible with most modern microcontrollers, having been designed to meet the requirements of the most popular microcontrollers in the industry today. It supports both 5 V and 3 V supply lines, allowing for it to be used in a variety of different systems. Additionally, its small SOIC package makes it extremely attractive for applications which require a small form factor.

In terms of its working principle, the MIC809TUY-TR monitors the voltage on the power supply rail and compares it with its internal threshold. If the voltage drops below the internal reset threshold, the MIC809TUY-TR will generate a reset signal, which in turn will reset the system. The length of the reset signal is adjustable, allowing for the system to return to normal operation as quickly or as slowly as desired. Additionally, the MIC809TUY-TR also monitors the enable pin and generates a reset signal if the enable pin is not activated within a specified time frame. This additional built-in safety measure allows for additional protection against unanticipated power loss or system faults that the user may not be aware of.

The MIC809TUY-TR is so popular because of its ability to provide protection from reset and power failure events. Furthermore, its various adjustable and configurable parameters allow for it to be easily adapted to most any system design requirements. Additionally, its wide operating temperature range and low-power consumption make it a very attractive option for low-power applications. All in all, the MIC809TUY-TR is a very cost-effective way to provide system protection.
