FAQs
What is MAX690AEPA+?
The MAX690AEPA+ is a precision, microprocessor supervisory circuit designed by Maxim Integrated. It provides power-supply monitoring and reset generation for microprocessor systems, ensuring reliable operation and protection against power supply-related issues.
How Does MAX690AEPA+ Work?
The MAX690AEPA+ works by continuously monitoring the power supply voltage and generating a reset signal to the microprocessor when the voltage falls below a predefined threshold. This ensures that the microprocessor resets and initializes correctly in the event of power supply disturbances, preventing erratic operation or data corruption.
How Many Pins does MAX690AEPA+ have and What are the Functions of the Pinout Configuration?
The MAX690AEPA+ is housed in an 8-pin PDIP (Plastic Dual In-Line Package) or SOIC (Small Outline Integrated Circuit) package. The pinout configuration includes:
- VCC: Power supply input pin.
- GND: Ground pin.
- RESET: Reset output pin for the microprocessor.
- MR: Manual reset input pin for external reset control.
- WDO: Watchdog output pin for monitoring microprocessor activity.
- TOUT: Temperature output pin for sensing the device temperature.
What are the Pros and Cons of MAX690AEPA+?
Pros:
- Power-Supply Monitoring: Ensures reliable operation by monitoring power supply voltages.
- Reset Generation: Automatically generates a reset signal when power supply voltage falls below threshold, preventing erratic operation.
- Watchdog Timer: Includes a watchdog output for monitoring microprocessor activity and detecting software failures.
- Manual Reset Input: Allows external control of the reset function for added flexibility.
- Temperature Output: Provides a temperature output for temperature monitoring.
Cons:
- External Components: May require external components such as resistors and capacitors for the timing and threshold settings.
- Package Options: Limited to PDIP and SOIC package options, which may not be suitable for all designs.
Are There Any Equivalents/Alternatives to MAX690AEPA+ for Recommendation?
- The MAX811 from Maxim Integrated is a similar microprocessor supervisory circuit offering comparable features.
- Alternatives to the MAX690AEPA+ include the LTC690 from Linear Technology and the ADM803 from Analog Devices.
