MAX811REUS

The MAX811REUS is a microprocessor supervisory circuit designed to monitor power supplies in digital systems. It ensures that a system does not execute code when the power supply is below a safe operational level, thus preventing erratic system behavior. The device typically integrates features such as a reset output to signal the microprocessor to restart or enter a safe mode when the voltage drops below a predefined threshold. It also includes a manual reset input, allowing for external control over the reset line.
The MAX811REUS operates with low supply current and is available in various threshold voltage options to suit different system requirements. Packaged in a compact SOT-23 form factor, it is ideal for space-constrained applications. These features make it a reliable choice for maintaining system integrity in power-sensitive applications, ensuring the system only operates under proper voltage conditions.

The MAX811REUS is a microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems and provide a reset signal to maintain proper operation. Key features include:
1. Reset Functionality: It asserts a reset signal whenever the power supply voltage falls below a preset threshold. This helps in preventing the microprocessor from executing erroneous codes during power-up, power-down, or brown-out conditions.
2. Precision Monitoring: Offers precise voltage monitoring, typically with ±2% accuracy, ensuring reliable system performance by accurately detecting under-voltage conditions.
3. Low Supply Current: Consumes minimal power, typically less than 10 µA, making it ideal for battery-powered applications.
4. Manual Reset Input: Includes an input pin that allows for an external reset to be initiated, providing additional flexibility and control.
5. Active-Low Reset Output: Provides an active-low reset which is suitable for most microprocessor designs.
6. Fast Propagation Delay: Features a fast propagation delay, ensuring quick response to voltage changes.
7. Package Options: Available in small-size SOT23 packages, facilitating compact design implementations.
These features make the MAX811REUS suitable for ensuring reliable operation in various digital applications by preventing undesired processor behavior due to power issues.

The MAX811REUS is typically available in a SOT-143 package type.

The MAX811REUS is a microprocessor supervisory circuit designed to monitor the power supply and reset a microprocessor during power-up, power-down, and brownout conditions. It comes in a small SOT-143 package.
Pin Count:
The MAX811REUS has 4 pins.
Pin Functions:
1. GND (Pin 1): Ground reference for the device.
2. RESET (Pin 2): Active-low reset output. It asserts low when VCC falls below the reset threshold and remains low for a fixed period after VCC exceeds the threshold.
3. VCC (Pin 3): Power supply input. This pin monitors the voltage level to determine when to trigger a reset.
4. N.C. (Pin 4): No Connection. This pin is not internally connected and can be left floating or connected to GND.
The MAX811REUS ensures that the microprocessor is properly reset and operates reliably by preventing erratic operation during power supply fluctuations.
