The MIC809SYC3-TR is an integrated circuit (IC) component that offers a reset function for microcontroller systems. It ensures reliable and controlled operation during power-up, power-down, and brownout conditions. Here's an overview of the key features of the MIC809SYC3-TR:
1. Voltage monitoring: The IC monitors the supply voltage and asserts a reset signal when it detects a voltage below a preset threshold. This ensures that the microcontroller is reset and put into a known state during power-up and brownout conditions, preventing erratic behavior.
2. Precision voltage reference: It utilizes a precision voltage reference to set the threshold level for voltage monitoring. This allows for accurate and consistent detection of voltage variations, ensuring reliable operation of the microcontroller.
3. Adjustable time delay: The MIC809SYC3-TR offers an adjustable time delay before releasing the reset signal after the supply voltage has returned to an acceptable level. This delay ensures that the power supply stabilizes before the microcontroller resumes operation, preventing premature restarts.
4. Active-low reset output: When the monitored voltage falls below the threshold, the IC asserts an active-low reset signal to bring the microcontroller into a reset state. This output is typically connected to the reset input of the microcontroller.
5. Low supply current: The IC has a low supply current requirement, which minimizes power consumption and enables efficient operation in battery-powered applications
