The MIC5020YM is a versatile power supply supervisor IC component designed by Micrel Inc. It offers a comprehensive range of features to ensure reliable and efficient power supply supervision in various applications.
One of the key features of the MIC5020YM is its ability to monitor two voltage levels simultaneously. It has two separate voltage comparator sections, each with its own reference voltage input and adjustable hysteresis. This allows the IC to accurately monitor different voltage levels and trigger a reset signal when the voltage goes above or below the set thresholds.
The operating voltage range of the MIC5020YM is from 3V to 40V, making it suitable for a wide range of power supply applications. It also has built-in power-on reset (POR) circuitry that generates a reset pulse when the input voltage rises above the POR threshold, ensuring a controlled startup of the system.
To enhance flexibility, the MIC5020YM provides multiple options for configuring the reset output and timer. It offers a choice between active high and active low reset outputs, allowing compatibility with different systems. The reset output can be manually enabled or disabled using an external control pin, providing control over the system reset functionality.
Furthermore, the MIC5020YM includes a built-in adjustable watchdog timer to detect system malfunctions. The watchdog timer requires a periodic signal input to prevent system lock-ups
