MAX809LEUR

The MAX809LEUR is a voltage monitoring integrated circuit (IC) designed to safeguard microprocessor systems by providing a reset signal whenever the system’s power supply voltage dips below a specified threshold. This IC is part of the MAX809 series, produced by Maxim Integrated, and is particularly used in systems that require reliable monitoring of supply voltages to ensure stable and predictable operation.
Key features of the MAX809LEUR include a precision voltage detector with a fixed threshold voltage, low supply current, and a push-pull output. The device generates an active-low reset signal (RESET) when the monitored voltage falls below its preset trigger level. This reset signal holds the microprocessor in a reset state until the voltage returns to a safe level, allowing for a stable system power-up.
The MAX809LEUR is typically housed in a small SOT-23 package, making it suitable for space-constrained applications. It is commonly used in consumer electronics, automotive systems, and other applications where maintaining processor integrity in the event of power fluctuations is crucial.

The MAX809LEUR is a microprocessor supervisory circuit designed to monitor the power supply voltage of digital systems and microcontrollers. Here are its key features:
1. Voltage Monitoring: It monitors the power supply voltage and asserts a reset when the voltage drops below a specified threshold.
2. Reset Function: Provides a reset output to reset the microprocessor during power-up, power-down, and brownout conditions. The reset is active low.
3. Precision Thresholds: It has a fixed voltage threshold with high precision to ensure reliable operation.
4. Reset Timeout Period: Offers a fixed reset timeout period, typically around 140ms, to ensure the system has fully stabilized before the reset is released.
5. Low Supply Current: Consumes very low supply current, making it suitable for battery-powered applications.
6. Small Package: Available in a compact SOT-23 package, which is ideal for space-constrained applications.
7. Temperature Range: Operates over a wide temperature range, typically from -40°C to +85°C, making it suitable for various environmental conditions.
These features make the MAX809LEUR a reliable choice for ensuring system stability in various electronic applications.

The MAX809LEUR is typically available in a SOT-23 package type. This is a small, surface-mount package commonly used for integrated circuits, offering compact size and ease of assembly on printed circuit boards.

The MAX809LEUR is a supervisory circuit designed to monitor the supply voltage in microcontroller systems. It is housed in a small SOT-23 package, which typically has 3 pins. The primary function of the MAX809LEUR is to reset the microcontroller when the supply voltage falls below a specified threshold, thus ensuring reliable operation during power-up, power-down, and brownout conditions. The pin configuration is usually as follows:
1. Pin 1 (GND): Ground pin, connected to the system ground.
2. Pin 2 (RESET): Output pin that provides an active-low reset signal to the microcontroller. The reset signal is asserted when the monitored voltage falls below the threshold and remains asserted for a minimum period after the voltage returns above the threshold.
3. Pin 3 (VCC): Supply voltage pin, where the monitored voltage is connected.
The MAX809LEUR is valued for its low power consumption and precision voltage monitoring, providing a straightforward and efficient way to implement power supply supervision.
