Description

The MAX813LCPA+ is an electronic component model in the category of supervisors. It is a microprocessor (µP) supervisory circuit that helps monitor power-supply and battery functions in µP systems. This device is designed to improve system reliability and accuracy by reducing complexity and the number of components needed compared to separate ICs or discrete components.

Specifications and features

The MAX813LCPA+ provides several functions to enhance system performance:

1. A reset output during power-up, power-down, and brownout conditions
2. An independent watchdog output that goes low if the watchdog input has not been toggled within 1.6 seconds
3. A 1.25V threshold detector for power-fail warning, low-battery detection, or monitoring a power supply other than +5V
4. An active-low manual-reset input

Additionally, the MAX813LCPA+ is identical to the MAX705, except RESET is provided instead of RESET. The MAX707/MAX708 are the same as the MAX705/MAX706, except an active-high reset is substituted for the watchdog timer.

Two supply-voltage monitor levels are available for the MAX813LCPA+. It generates a reset pulse when the supply voltage drops below 4.65V. The MAX706/MAX708, on the other hand, generate a reset pulse below 4.40V. All four versions are available in 8-pin DIP, SO, and µMAX packages.

Application Scenarios

The MAX813LCPA+ is suitable for various applications, including:

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