Microchip Technology MIC6315-30D3UY-TR Supervisory Circuit

The MIC6315-30D3UY-TR is a highly precise supervisory circuit designed by Microchip Technology to monitor power supplies in digital systems. This device is particularly engineered to ensure that the system's voltage levels remain within operational thresholds, safeguarding the system against potential damage caused by unpredictable power fluctuations.

This supervisory circuit features a factory-trimmed threshold voltage of 3.0V, which makes it ideal for 3.3V powered systems. Its tight threshold accuracy and low power consumption make it a reliable choice for portable and battery-operated devices. The MIC6315-30D3UY-TR is capable of asserting a reset signal whenever the V_CC supply voltage drops below the 3.0V threshold, ensuring the system microcontroller or processor initializes in a known state after a power failure or during power-up.

One of the key attributes of the MIC6315-30D3UY-TR is its built-in delay feature. The reset output remains asserted for a period after the supply voltage has risen above the threshold, providing the system with a stable amount of time to recover before resuming operation. This delay is achieved without the need for external components, simplifying the design and reducing the overall component count.

The device is offered in a compact, surface-mount SOT-23 package, making it suitable for space-constrained applications. Its temperature range extends from -40°C to +85°C, ensuring reliable operation under varying environmental conditions.

The MIC6315-30D3UY-TR also includes additional features such as a low supply current, typically 3.5 μA, which contributes to the conservation of battery life in portable applications. Furthermore, the device's active-low open-drain output allows for easy interfacing with other components within the system.

In summary, the MIC6315-30D3UY-TR from Microchip Technology is an essential component for any system that requires accurate monitoring of its power supply. Its precision, low power consumption, and compact design make it an excellent choice for designers looking to enhance system reliability and performance.
