Description

The LM809M3X-3.08 is a voltage supervisory circuit used in electronic systems to monitor and manage power supply voltage levels. It is designed to ensure that microcontrollers or other digital systems operate within their specified voltage ranges by resetting them during situations of undervoltage. When the monitored voltage drops below a specified threshold, the LM809M3X-3.08 triggers a reset signal to the connected device, preventing malfunction or erratic behavior due to insufficient voltage.
Key features of the LM809M3X-3.08 include low power consumption, precision monitoring with tight voltage thresholds, and a manual reset capability. The device offers a reset timeout period to ensure systems are stable before normal operation resumes. It is typically housed in a small SOT-23 package, making it suitable for space-constrained applications. The "3.08" in its designation indicates the specific voltage threshold (3.08V) it monitors. This component is commonly used in applications such as computers, embedded systems, and other digital electronics where reliable performance is critical.

Pinout

The LM809M3X-3.08 is a microprocessor supervisory circuit, specifically a reset generator, which is used to monitor the supply voltage in microprocessor systems. It typically functions to reset the microprocessor during power-up, power-down, or brownout conditions.
The LM809M3X-3.08 comes in a 3-pin SOT-23 package. The pin functions are as follows:
1. GND (Ground): This pin is connected to the ground of the system.
2. VCC (Power Supply): This pin is connected to the supply voltage that needs to be monitored.
3. RESET (Output): This active-low output pin provides the reset signal to the microprocessor. The RESET pin goes low when the supply voltage falls below the specified threshold (3.08V in this case) and stays low for a fixed period after the supply voltage exceeds the threshold to ensure a stable reset.
These 3 pins provide a simple yet effective solution for ensuring reliable operation of microprocessor systems by preventing erratic behavior during voltage fluctuations.
