Microchip Technology MIC810MUY-TR Voltage Supervisor

The MIC810MUY-TR from Microchip Technology is a compact, highly reliable voltage supervisor device designed to monitor power supplies in digital systems. It provides an essential protection mechanism by asserting a reset signal whenever the VCC supply voltage drops below a predetermined threshold, ensuring that the microprocessor, FPGA, or other digital system operates within its specified voltage range.

This particular model, housed in a space-saving SOT-23-3 package, is perfect for portable and space-constrained applications such as handheld devices, IoT endpoints, and wearables. The MIC810MUY-TR offers a fixed threshold voltage of 4.38V, which is suitable for 5V systems, and ensures that the devices it protects are not exposed to potentially damaging undervoltage conditions.

Key features of the MIC810MUY-TR include:

• Low Power Consumption: The device is designed for battery-operated systems with its low quiescent current, thereby extending battery life.
• Precision Voltage Monitoring: It offers a tight threshold voltage accuracy, ensuring reliable monitoring and system protection.
• Manual Reset Input: This feature allows a manual reset to be triggered, providing additional system control.
• Reset Timeout: A built-in delay ensures that the system has sufficient time to stabilize before the reset is de-asserted.
• Immunity to Short VCC Transients: The device is designed to ignore brief voltage dips, preventing unnecessary resets due to transient conditions.

The MIC810MUY-TR is also characterized by its fast response time, which allows it to react quickly to changes in VCC, and its open-drain reset output, which can be connected to different voltage levels, making it highly versatile for various system designs.

Overall, the MIC810MUY-TR voltage supervisor is a critical component for any system that requires reliable operation and protection against undervoltage conditions. Its small footprint, precision monitoring capabilities, and low power consumption make it an excellent choice for designers looking to enhance the stability and robustness of their electronic products.
