The MAX807LCWE+ is a sophisticated microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in conjunction with a 5V-powered circuit.
This device is particularly adept at maintaining system integrity through its multiple features. It offers a precision voltage monitor for the power supply, a microprocessor reset system during power-up, power-down, and brownout conditions, and a debounced manual reset input. The MAX807LCWE+ is ideal for use in systems that require a high level of dependability and where space is at a premium.
Key Features:
- Power Supply Monitoring: Ensures that the system microprocessor is reset to a known state during power-up, power-down, or brownout conditions.
- Manual Reset Input: A debounced input allows for a manual reset, providing an additional layer of control for system operators.
- Backup Battery Switchover: No external diodes are needed for backup battery switchover, simplifying design and saving board space.
- Watchdog Timer: A watchdog timer is integrated to keep the system running smoothly and to reset the µP if it fails to strobe within a preset time period.
- Low Power Consumption: The device is designed for efficient power usage, contributing to overall energy savings in the system.
Applications:
- Computers and Controllers
- Intelligent Instruments
- Automotive Systems
- Critical µP Power Monitoring
The MAX807LCWE+ comes in a 16-pin wide SO package, making it easy to integrate into a variety of system designs. With its robust set of features and Maxim Integrated's reputation for quality, this supervisory circuit is an excellent choice for designers looking to enhance system reliability and performance.
