Product Overview: MAX805LCSA+ from Maxim Integrated

The MAX805LCSA+ 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 that require voltage monitoring and battery control functions. This device is ideal for use in a wide range of applications, including computers, controllers, intelligent instruments, and critical µP power monitoring.

The MAX805LCSA+ ensures that the µP is only operational when the power supply is within acceptable limits. It achieves this by monitoring the power supply voltage and asserting a reset if the supply voltage drops below a preset threshold. The reset output remains asserted for a period after the supply voltage exceeds the threshold, ensuring the µP has adequate time to initialize and stabilize after a power failure.

Key features of the MAX805LCSA+ include:

• Precision Monitoring: This device offers precision voltage monitoring with factory-set reset threshold voltages ranging from 2.5V to 5V, catering to a variety of system voltage requirements.
• Power-On Reset: It provides a power-on reset signal to the µP during power-up, power-down, and brown-out conditions, ensuring the system starts in a known state.
• Manual Reset Capability: The inclusion of a manual reset input allows for a system reset to be triggered with an external push-button or logic signal.
• Low Power Consumption: With its low supply current draw, the MAX805LCSA+ is suitable for battery-powered applications, extending battery life.
• Compact Form Factor: Housed in a compact 8-pin SO package, the device saves valuable board space in space-constrained applications.

The MAX805LCSA+ is available in a wide operating temperature range of -40°C to +85°C, which allows for use in diverse environments. Its robust design and ease of integration make it a go-to solution for system designers looking to enhance system integrity through reliable voltage monitoring and reset functions.

Maxim Integrated's commitment to quality ensures that the MAX805LCSA+ meets the rigorous standards required for mission-critical applications, making it a trustworthy component for your digital systems.
