Features
1. Reset Functionality: Provides a reset output during power-up, power-down, and brownout conditions. It ensures the microprocessor is properly reset to prevent errors.
2. Precision Monitoring: Monitors the supply voltage with a typical threshold accuracy of ±2%.
3. Manual Reset Input: Allows for external triggering of the reset function via a push-button or other control input.
4. Watchdog Timer: Monitors microprocessor activity and resets the system if no activity is detected within a predetermined period, preventing system hang-ups.
5. Low Supply Current: Consumes minimal power, making it suitable for battery-powered applications.
6. Small Package: Available in a compact 8-pin SOIC package, facilitating easy integration into various designs.
7. Temperature Range: Operates over a wide temperature range, typically from -40°C to +85°C, ensuring reliability in diverse environments.
These features make the MAX706TCSA ideal for applications requiring robust supervision of microprocessor systems.
Pinout
1. VCC (Pin 8): Power supply input.
2. GND (Pin 4): Ground.
3. RESET (Pin 1): Active-low reset output. It goes low when VCC falls below the reset threshold and remains low for a predetermined period after VCC exceeds the reset threshold.
4. RESET (Pin 5): Active-high reset output.
5. WDI (Pin 7): Watchdog input. If a pulse is not detected within 1.6 seconds, RESET will be triggered.
6. MR (Pin 6): Manual reset input. A low signal here triggers a reset.
7. PFO (Pin 3): Power-fail output. Indicates an impending power failure.
8. PFI (Pin 2): Power-fail input. Monitors voltage level for power-fail detection.
This IC is used for ensuring reliable operation by supervising the reset, providing watchdog functionality, and monitoring power supply voltages.
