Product Overview: MIC810SUY-TR from Microchip Technology

The MIC810SUY-TR is a high-quality voltage supervisor component designed and manufactured by Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This device is primarily used to monitor the power supply voltage of microcontrollers and digital systems, ensuring that the system operates reliably within its specified voltage range. It is an essential component for applications that require a high level of precision and stability in their power supply.

With its tiny, space-saving SOT-23 package, the MIC810SUY-TR is an ideal choice for space-constrained applications. It provides a fixed threshold voltage of 4.38V, which is suitable for monitoring 5V power supplies. The device features an active-low reset output, which remains asserted until the supply voltage reaches the designated reset threshold voltage and then maintains the reset condition for a minimum of 140ms after the supply voltage rises above the threshold. This ensures that the system has sufficient time to stabilize before normal operation resumes.

The MIC810SUY-TR is characterized by its low power consumption, making it an excellent choice for battery-operated devices. It is designed to operate over a wide temperature range of -40°C to +85°C, allowing it to function reliably in harsh environmental conditions. Additionally, the device has a fast response time to power supply transients, which helps to protect the system against short duration voltage dips and spikes.

Microchip Technology has equipped the MIC810SUY-TR with a manual reset input that provides a direct way to initiate a system reset. This feature can be very useful during system maintenance or when a controlled system reboot is required. The device also offers immunity to short VCC transients, which is critical for avoiding false resets that can lead to system malfunctions.

Overall, the MIC810SUY-TR voltage supervisor is a robust and reliable solution for managing system power-up and power-down sequences, providing an extra layer of protection for sensitive electronic systems. Its compact form factor, low power consumption, and high precision make it an indispensable component for engineers looking to enhance system reliability and performance.
