MIC2775-29YM5-TR

The MIC2775-29YM5-TR is a voltage supervisor and reset IC manufactured by Microchip Technology. This device is designed to monitor power supply voltages and provide a reset signal to microcontrollers and other digital devices when the supply voltage falls below a specified threshold.

Key Features:

1. Voltage Monitoring: The MIC2775-29 monitors the supply voltage and is specifically designed to provide a reset signal when the voltage drops below 2.9V. This is crucial for ensuring that digital circuits operate reliably and do not enter an undefined state during power fluctuations.

2. Reset Output: The device features an active-low reset output, which means that the output signal goes low when the monitored voltage is below the threshold. This output can be connected directly to the reset pin of a microcontroller or other digital logic devices.

3. Reset Timeout: The MIC2775-29 includes a built-in reset timeout feature, which ensures that the reset signal remains active for a specified duration after the supply voltage has returned to a safe level. This delay helps to ensure that the system has stabilized before the microcontroller resumes operation.

4. Low Supply Current: The device is designed to operate with low supply current, making it suitable for battery-powered applications where power efficiency is critical.

5. Temperature Range: The MIC2775-29 is rated for operation over a wide temperature range, typically from -40°C to +125°C, making it suitable for industrial and automotive applications.

6. Package Type: The MIC2775-29YM5-TR is available in a compact 5-pin SOT-23 package, which is ideal for space-constrained designs. The small footprint allows for easy integration into various circuit layouts.

7. Applications: This voltage supervisor is commonly used in applications such as microcontroller reset circuits, power management systems, automotive electronics, and any other application where reliable voltage monitoring and reset functionality are required.

Electrical Characteristics:

• Supply Voltage Range: The device typically operates within a range of 1.5V to 5.5V.
• Reset Threshold Voltage: The reset threshold is fixed at 2.9V, ensuring consistent performance across different applications.
• Reset Delay Time: The reset delay time is typically in the range of milliseconds, allowing for quick recovery after a power interruption.

Conclusion:

The MIC2775-29YM5-TR from Microchip Technology is a reliable and efficient voltage supervisor and reset IC that provides essential functionality for ensuring the stability and reliability of digital circuits. Its compact size, low power consumption, and robust performance make it an excellent choice for a wide range of electronic applications.
