Additional Details

The MIC2788-XYMT TR supervisory circuit is a critical component in microprocessor-based systems. It monitors the supply voltage and asserts a reset signal when the voltage falls below a specified threshold, preventing the microprocessor from operating with insufficient power. The active-low reset output ensures that the microprocessor is held in reset until the supply voltage is stable. The manual reset input allows for external reset triggering. The low supply current minimizes power consumption, making it suitable for portable devices. The small SOT-23 package saves board space. The adjustable reset timeout allows for fine-tuning the reset duration. The supervisory circuit is commonly used in applications where reliable and stable operation of the microprocessor is essential. The tape and reel packaging (TR suffix) is designed for automated assembly.
