Maxim Integrated Product Overview: MAX807LEWE+

The MAX807LEWE+ from Maxim Integrated is a sophisticated microprocessor (µP) supervisory circuit designed to monitor power supplies and microprocessor activity in digital systems. It provides essential functions such as power-on reset control, watchdog timing, and manual reset capability. This product ensures reliable operation of microprocessor systems by providing a reset signal to the µP during power-up, power-down, and brown-out conditions.

Key Features:

• Power Supply Monitoring: The MAX807LEWE+ monitors the system voltage and asserts a reset to the microprocessor whenever it detects an out-of-tolerance condition, ensuring the µP starts in a known state.
• Watchdog Timer: A built-in watchdog timer keeps the microprocessor running smoothly. If the µP fails to strobe the watchdog within a preset timeout period, the device will issue a system reset, helping to recover from a software lock-up or other malfunction.
• Manual Reset Input: An external manual reset input allows for a reset to be triggered with an external switch or logic signal, providing an additional layer of system control.
• Low Power Consumption: Designed for energy-efficient applications, the MAX807LEWE+ operates with low power consumption, making it suitable for battery-powered devices.
• High Accuracy: This supervisory circuit maintains high reset threshold accuracy over temperature, ensuring reliable performance under varying conditions.
• Compact Package: The MAX807LEWE+ is available in a 16-pin wide SO package, which is ideal for space-constrained applications.

Applications:

The MAX807LEWE+ is versatile and can be used in a wide range of applications, including:

• Computers and Servers
• Embedded Systems
• Communication Equipment
• Portable/Battery-Powered Equipment
• Industrial Controllers

With its robust feature set and Maxim Integrated's reputation for quality, the MAX807LEWE+ is an excellent choice for designers looking to enhance system reliability and performance in their digital systems.
