MIC809SU-TR

MIC809SU-TR Description

The MIC809SU-TR is a high-performance power management integrated circuit (PMIC) designed by Microchip Technology. This supervisor IC is specifically tailored for monitoring a single voltage rail, ensuring reliable system operation by providing accurate voltage monitoring and reset functionality. The MIC809SU-TR is housed in a compact SOT23-3 package, making it ideal for space-constrained applications. It features a surface-mount mounting type and is available in a tape and reel (TR) package format, which is suitable for automated assembly processes.

MIC809SU-TR Features

• Single Voltage Monitoring: The MIC809SU-TR is designed to monitor a single voltage rail with a threshold voltage of 2.93V. This precision ensures that the system remains stable and reliable under varying power conditions.
• Active Low Reset Output: The reset output is active low, which is a common requirement in many digital systems. This feature allows the IC to reset the system when the monitored voltage falls below the threshold, ensuring proper initialization and operation.
• 140ms Minimum Reset Timeout: The IC provides a minimum reset timeout of 140ms, which is sufficient to ensure that the system has enough time to complete its reset sequence and stabilize before resuming normal operation.
• Moisture Sensitivity Level (MSL) 1: With an MSL rating of 1 (unlimited), the MIC809SU-TR is suitable for a wide range of environmental conditions, making it highly reliable and durable.
• Compliance and Safety: The MIC809SU-TR is REACH unaffected and classified under ECCN EAR99, ensuring compliance with international regulations and safety standards.
• Harmonized Tariff Schedule (HTSUS): The product is classified under HTSUS code 8542.39.0001, facilitating smooth import and export processes.
