The MAX806CSA from Maxim Integrated is a highly reliable microprocessor (µP) supervisory circuit designed 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 with +5V-powered circuits.

Key Features

• Precision Monitoring: This device features a precision voltage monitor that keeps a vigilant watch over the power supply levels, ensuring that the microprocessor is always operating under optimal conditions.
• Power-On Reset: The MAX806CSA generates a reset signal whenever the VCC supply voltage declines below a preset threshold, maintaining a reset output until VCC has returned to an acceptable level and a significant period has passed. This ensures a proper system reset and start-up sequence.
• Manual Reset Capability: A manual reset feature allows for a reset to be triggered with an external button or signal, providing additional system control and diagnostics flexibility.
• Low Power Consumption: Designed for power-sensitive applications, the device operates with very low quiescent current, which is crucial for battery-operated systems.
• Compact Package: The MAX806CSA comes in an 8-pin SOIC package, ideal for space-constrained applications.

Applications

This supervisory circuit is suitable for a wide range of applications where reliable system operation is critical. It is commonly used in:

• Computers and Controllers
• Intelligent Instruments
• Portable/Battery-Powered Equipment
• Embedded Systems

Technical Specifications

The MAX806CSA operates over a wide temperature range and features a reset threshold of typically 4.65V. The device is designed for systems that use a +5V power supply and require a reset pulse on power-up, brownout, or manual reset event.

Conclusion

As a product of Maxim Integrated, a trusted name in the development of integrated circuits, the MAX806CSA is a testament to the company's commitment to quality, reliability, and innovation. Whether you're designing a new system or upgrading an existing one, the MAX806CSA provides the necessary protection against power supply inconsistencies, thereby safeguarding your microprocessor-based applications.
