The MAX705ESA is a microprocessor supervisory circuit designed by Maxim Integrated to monitor the power supply voltage in microcontroller-based systems. It is targeted at applications where maintaining the integrity of the system's power supply is critical.
Some of the key features of the MAX705ESA include a precision voltage reference, a watchdog timer, a manual reset input, and a power-fail comparator. The voltage reference monitors the supply voltage and generates a reset signal if the voltage falls below a user-defined threshold. The watchdog timer provides additional protection by resetting the system if the microcontroller fails to periodically reset it.
The manual reset input allows the system to be reset externally, which can be useful during system testing or when troubleshooting. The power-fail comparator detects power supply glitches and can generate a reset signal to ensure that the system remains in a safe state.
The MAX705ESA operates over a wide supply voltage range, making it suitable for a variety of applications. It is available in a small, space-saving SOIC package, making it easy to integrate into existing designs. Additionally, the device consumes low quiescent current, making it suitable for battery-powered applications.
Overall, the MAX705ESA is a versatile and reliable microprocessor supervisory circuit that provides essential features for monitoring and maintaining the integrity of power supplies in a wide range of applications
