The MAX814NESA from Maxim Integrated is a compact, highly integrated microprocessor (µP) supervisory circuit designed to monitor power supplies and µP activity in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with 5V power supplies.
Key Features
- Precision Monitoring: The device features a precision voltage monitor that keeps a watchful eye on the system's power supply, ensuring that it remains within acceptable thresholds for reliable operation.
- Power-On Reset Control: Upon application of power, the MAX814NESA generates a reset signal to ensure that the µP starts in a known state. The reset signal remains asserted for a period after the power supply has reached its specified threshold, providing a stable start-up environment for the µP.
- Manual Reset Capability: An additional feature of this supervisory circuit is the manual reset input, which allows for a system reset to be triggered with an external button or logic signal.
- Low Power Consumption: Designed for power-sensitive applications, the MAX814NESA consumes minimal power, which helps to extend the life of battery-operated devices.
- Compact Package: The device comes in a small 8-pin SO package, making it ideal for space-constrained applications.
