The MAX809R is a microprocessor supervisory circuit primarily used for monitoring the supply voltage in microprocessor systems and generating a reset signal whenever the monitored voltage falls below a preset threshold. It typically comes in a 3-pin package, such as SOT23 or TO-92. The pin functions are as follows:
1. GND (Ground): This pin is connected to the system ground. It serves as the reference point for the other voltages in the circuit.
2. VCC (Supply Voltage): This pin is connected to the power supply that needs to be monitored. The MAX809R supervises this voltage to ensure it stays above the threshold.
3. RESET: An active-low output, this pin provides the reset signal. When the monitored voltage drops below the threshold, the RESET pin is driven low, signaling the microprocessor to restart or enter a safe state. Once the voltage returns above the threshold and the internal reset timeout period elapses, the RESET pin goes high.
The MAX809R is valued for its low power consumption and precise voltage monitoring, which makes it effective in enhancing system reliability.
