Description
The MAX708RESA-TG is a microprocessor supervisory circuit designed to monitor power supplies in microprocessor systems. It ensures reliable system operation by providing essential functions such as reset output during power-up, power-down, and brownout conditions. The device also features a watchdog timer, which resets the microprocessor if it fails to operate correctly within a specified time frame, and a manual reset input for external activation. Operating over a voltage range of 4.65V to 5.5V, the MAX708RESA-TG is particularly suitable for 5V systems.
The device offers high precision with a reset threshold accuracy of ±2%, ensuring reliable detection of supply voltage anomalies. Its low quiescent current makes it ideal for battery-powered applications. Additionally, the MAX708RESA-TG includes a power-fail comparator for early warning of impending power loss, allowing the system to save data and prepare for an orderly shutdown. Packaged in a compact, surface-mount form, it integrates seamlessly into a wide range of electronic applications, enhancing system stability and reliability.
