Microchip Technology MIC803-31D2VC3-TR Voltage Supervisor

The MIC803-31D2VC3-TR is a highly precise, compact, and reliable voltage supervisor designed by Microchip Technology, a leader in microcontroller and analog semiconductors. This device is specifically engineered to monitor voltage levels and provide a reset signal to microcontrollers (MCUs) and other digital systems, ensuring proper operation during power-up, power-down, and brown-out conditions.

This voltage supervisor is a part of the MIC803 series, which is known for its small size and low power consumption, making it an ideal choice for portable and battery-operated applications. The MIC803-31D2VC3-TR comes in a 3-pin SOT-23 package, which is suitable for space-constrained designs.

The key features of the MIC803-31D2VC3-TR include:

• Reset Threshold Voltage: It has a precise threshold voltage of 3.1V, which is ideal for 3.3V systems, ensuring that the system has a stable power supply before allowing the processor to start.
• Reset Timeout Delay: The device provides a 140ms (minimum) reset timeout delay, which ensures that the system has sufficient time to stabilize before the reset condition is deasserted.
• Low Supply Current: With a low supply current of 3.5µA, it is highly energy-efficient, making it perfect for power-sensitive applications.
• Open Drain Output: The reset output is of open-drain type, allowing it to be pulled up to a voltage higher than VCC, offering flexibility in interfacing with different logic levels.
• Temperature Range: It operates over an industrial temperature range of -40°C to +85°C, suitable for harsh environments.

This device is particularly useful in applications where it is critical to maintain the integrity of the system's operation, such as in embedded systems, computers, data storage, and telecommunications equipment. The MIC803-31D2VC3-TR is available in tape and reel packaging, denoted by the suffix '-TR', which facilitates automatic placement and assembly processes in high-volume production environments.

By integrating the MIC803-31D2VC3-TR into your design, you can enhance system reliability and prevent data corruption due to unexpected power fluctuations, ensuring that your applications run smoothly and without interruption.
