Features
1. Voltage Monitoring: Monitors the supply voltage and provides a reset to the microprocessor during power-up, power-down, and brownout conditions.
2. Reset Output: Offers a push-pull reset output with a guaranteed active state for VCC as low as 1V.
3. Manual Reset Input: Includes a manual reset input for user-initiated resets.
4. Watchdog Timer: Features a watchdog timer that prompts a reset if the microprocessor fails to toggle the watchdog input within a specified time frame.
5. Low Supply Current: Consumes minimal power, making it suitable for battery-powered applications.
6. Precision Threshold: Provides a precision voltage threshold for accurate monitoring.
7. Temperature Range: Operates over an extended temperature range, enhancing suitability for various applications.
These features make the MAX708ESA-TG ideal for ensuring reliable operation in systems that demand precise voltage monitoring and robust reset capabilities.
Pinout
Here are the pin functions:
1. VCC: Power supply input.
2. GND: Ground reference for power supply.
3. RESET: Reset output that goes low when VCC falls below the reset threshold or when manual reset is activated.
4. MR: Manual Reset input. Activating this input generates a reset signal.
5. WDI: Watchdog Input. Used to monitor the microprocessor's activity and trigger a reset if the microprocessor fails to respond.
6. WDO: Watchdog Output. Provides an indication of a watchdog timeout.
7. PFO: Power-fail Output. Indicates that the power-fail threshold has been reached.
8. PFI: Power-fail Input. Used to monitor an unregulated power supply voltage.
The MAX708 is designed to ensure system reliability by monitoring supply voltage levels and providing a reliable reset signal during power-up, power-down, and brownout conditions.
