The MAX696CWE+ is a high-performance 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 systems with +5V powered µPs.

Key Features

• Precision Monitoring: This device offers precise monitoring of +5V power supplies to ensure that the system's microprocessor is always operating under optimal power conditions.
• Reset Output: The MAX696CWE+ includes a reset output which remains asserted for a minimum of 200ms after VCC has risen above the reset threshold. This feature guarantees that the µP starts up in a known state.
• Battery Backup: It features a battery backup switching for CMOS RAM, CMOS µP, or other low-power logic.
• Watchdog Timer: A watchdog timer is built-in, which must be periodically reset by the correct operation of the µP to prevent system failures.
• Manual Reset: Users can trigger a manual reset, allowing for greater control and diagnostic capabilities.
• Compact Size: The MAX696CWE+ comes in a compact 16-pin Wide SO package, saving valuable board space in dense system designs.

Applications

With its robust feature set, the MAX696CWE+ is ideal for use in a variety of applications, including:

• Computers
• Controllers
• Intelligent Instruments
• Automotive Systems
• Critical µP Power Monitoring

Technical Specifications

The device operates over a wide temperature range and has the following technical specifications:
