Pinout
The MIC811SUY-TR is a microprocessor supervisory circuit with a 3-pin configuration. Its primary function is to monitor the supply voltage in microprocessor systems and provide a reset signal whenever the monitored voltage falls below a specified threshold. This helps in protecting the microprocessor from operating under inadequate voltage levels, which can lead to erratic operation or data corruption.
The three pins typically are:
1. VCC: This is the supply voltage pin. It is the voltage being monitored by the circuit.
2. GND: Ground pin, which completes the circuit.
3. RESET: This output pin provides the reset signal. It is usually an active-low output that asserts when the voltage on the VCC pin drops below the threshold level and remains asserted for a fixed time period after the voltage returns to normal.
The MIC811SUY-TR ensures reliable system reset and prevents malfunction by keeping the microprocessor in a reset state during power-up, power-down, and brownout conditions.
