Microchip Technology's MIC811TU-TR Voltage Supervisor

The MIC811TU-TR is a high-quality voltage supervisor device designed and manufactured by Microchip Technology. This small yet powerful component is essential for managing system integrity by monitoring the power supply voltage of digital systems. It ensures that microprocessors, microcontrollers, and other digital systems reset properly during power-up, power-down, and brown-out conditions.

This voltage supervisor is provided in a compact 3-pin SOT-23 package, making it suitable for space-constrained applications. The MIC811TU-TR is designed to support a threshold voltage of 4.38V, which is ideal for systems operating at 5V power supply levels. Its precision monitoring capability allows it to maintain system reliability and prevent improper operation due to fluctuations or dips in the power supply.

One of the key features of the MIC811TU-TR is its active-low reset output. Upon detecting a voltage that falls below the threshold level, the device asserts a reset signal, which remains active until the voltage returns to an acceptable level and for a period after that, ensuring the system has stabilized. This reset delay time is internally set, removing the need for external components and simplifying circuit design.

Another advantage of the MIC811TU-TR is its low power consumption, making it suitable for portable and battery-operated devices where power efficiency is critical. The device also includes immunity to short duration transients on the monitored supply, enhancing its robustness in noisy environments.

With its built-in hysteresis to prevent erratic reset operation, the MIC811TU-TR from Microchip Technology is a reliable solution for system management. It is widely used in applications such as computers, embedded systems, storage systems, and other electronic products that require precise voltage monitoring and reset functions.

Overall, the MIC811TU-TR is a testament to Microchip Technology's commitment to providing high-quality, reliable semiconductor products that enhance the performance and stability of electronic systems across various industries.
