Pinout Description (SOT-23-5 Package) Pin # Pin Name Function Description 1 Vcc Positive supply voltage input (typically 2V to 6V). 2 GND Ground pin, provides the reference ground for the IC. 3 Reset Active low output. This pin goes low to indicate a reset condition. 4 Threshold Input pin used to set the threshold voltage for the reset signal. 5 NC No Connection, this pin is not used for electrical connections in the circuit.2. Pin Function Detailed Explanation
Pin 1: Vcc Function: This is the power supply input pin. The device operates with a supply voltage between 2V and 6V. Connecting this pin to the appropriate supply voltage is crucial for the IC’s functionality. Usage: This pin should be connected to a stable voltage source. Ensure the voltage remains within the specified range to avoid malfunction. Pin 2: GND Function: Ground pin for the IC. It serves as the reference point for all voltages within the device. Usage: The GND pin should be connected directly to the ground of the system. It is essential for proper operation. Pin 3: Reset Function: The Reset pin is an active-low output. When the monitored voltage falls below the preset threshold (set by the Threshold pin), this pin will be pulled low to indicate a reset condition. Usage: This pin is typically connected to the reset input of a microcontroller or other logic circuitry to trigger a reset in case of a fault or power-down condition. Pin 4: Threshold Function: This pin is used to set the threshold voltage for the reset signal. When the supply voltage drops below this threshold, the Reset pin will go low, indicating a fault or reset condition. Usage: A resistor divider or external reference voltage can be used to set the threshold voltage for reset. It determines the point at which the system needs to be reset. Pin 5: NC (No Connection) Function: This is a non-functional pin in the MAX809SN232T1G, meaning it is not used for any electrical connection. It can be left unconnected or grounded. Usage: This pin should be left unconnected as it is not required for the IC’s operation.3. FAQ (Frequently Asked Questions)
