Features
1. Reset Functionality: It provides a reset signal to the microprocessor during power-up, power-down, and brownout conditions to ensure reliable system operation.
2. Precision Monitoring: It monitors the supply voltage and asserts a reset if the voltage drops below a specified threshold, typically at a 2.32V threshold level for this variant.
3. Low Supply Current: The device consumes minimal power, making it suitable for battery-operated applications.
4. Manual Reset Input: It includes a manual reset input for external reset triggering.
5. Push-Pull Output: The device features a push-pull active-low reset output.
6. Small Package: It is available in a small SOT-23 package, ideal for compact designs.
7. Wide Operating Temperature Range: It operates effectively over a wide temperature range, suitable for various environmental conditions.
These features make the MAX809SN232T1G a reliable choice for maintaining consistent operation and protecting microprocessor-based systems.
Pinout
1. Pin 1 (GND): Ground pin, connected to the system ground.
2. Pin 2 (RESET): This is the reset output pin. It asserts a reset signal when the monitored voltage falls below the specified threshold. The reset signal remains asserted for a fixed time period after the voltage exceeds the threshold.
3. Pin 3 (VCC): Supply voltage pin, connected to the voltage that needs to be monitored.
These devices are commonly used to ensure reliable operation of microprocessors and microcontrollers by providing a stable reset signal during power instability.
