MIC811MU TR is a three pin general purpose reset circuit package in the form of SOT-23-5 produced by Micrel Semiconductor Corporation. This device is a part of the Supervisors product family and is used for early reset warning, to reset the system in case of over-current activity, or as a reset watchdog. It is a versatile system for monitoring and control, suitable for a wide range of systems, including those requiring high power management, or those requiring precision voltage monitoring.

The MIC811MU TR integrates 2.25V to 5.5V DC supply voltage with an over-voltage reset designed at 3.2V. It offers two independent power-on reset (POR) lengths: short output pulse, and long output pulse. The short pulse is designed to assure that the power supply has works over the ideal voltage and ensures that the system is capable of resetting. The long pulse output is designed to reset and reset the system or the IC in case of an over-current activity. The MIC811MU TR also provides an input for an adjustable reset timer, which can be set for a reset time between 0.1 seconds and 4 seconds.

The reset output in the MIC811MU TR is an open drain driven with an internal push-pull connection. It is designed to indicate when the reset output is active. The reset status can be one of three states: low, high, and pulsed. When the reset output is low, the reset is considered cleared. When the reset output is high, the reset is considered active. When the reset output is pulsed, the reset is considered hit.

The MIC811MU TR offers an adjustable reset time delay, which ensures a system reset when the voltage rises above its over-voltage reset level. This reset circuit package also provides an open drain output for the reset input, which can be used to reset the system in case the over-voltage reset is triggered. In addition, MIC811MU TR also offers an adjustable reset timer feature to reset the system, based upon the load current. The load current can be used to reset the system faster than the other features of the MIC811MU TR.

The MIC811MU TR is also designed to provide a windowed watchdog, which allows the system to reset itself in case of a reset fault or an unexpected elimination of the reset signal. This feature is designed to prevent the system from entering an indefinite loop or surging current due to the exact reset signal not being present. The MIC811 MU TR offers adjustable reset times and signal lengths, which allows the engineers to customize the reset signals to fit the system requirements.

The MIC811MU TR is designed to provide high precision monitoring of voltage and current, using the over-voltage reset feature, reset inhibitor, and windowed reset timer. The reset inhibitor works in conjunction with the other features of the MIC811MU TR to ensure that a system is reset only if the voltage rises above the set over-voltage reset level. This reset minimizes the risk of reset failure due to changes in power levels, and allows for more precise reset management. The adjustable reset timer, which is meant to reset the system upon a specific load current, can be used to reset a system faster than is possible with other reset systems. Finally, the windowed reset timer is designed to reset the system before an unexpected elimination of the reset signal occurs, preventing the possibility of having an indefinite loop or an increased current surge.

The MIC811MU TR is an ideal solution for systems requiring an early warning, reset, or system reset due to over-current activity, with high power management resolution or precise voltage monitoring. Its features make it a versatile system for managing reset signals, controlling over-voltage reset levels, reseting to a precise pre-specified current, and providing reset warnings and inhibitions. The MIC811MU TR is a great choice for the reset circuit needs of a wide range of systems.
