Maxim Integrated MAX6806UR23 Microprocessor Reset Circuit

The Maxim Integrated MAX6806UR23 is a highly compact, single-supply, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +2.5V to +5.0V powered circuits.

This tiny supervisory circuit is ideal for monitoring the power supply status in µP and digital systems, providing a reset signal to the host processor whenever the supply voltage drops below a preset threshold. The reset output remains asserted for a minimum of 140ms after V_CC has risen above the reset threshold level, ensuring the system has sufficient time to stabilize after a power disturbance.

Key Features:

• Precision Monitoring: The device features a factory-trimmed reset threshold at 2.32V, tailored for 2.5V-powered applications.
• Low Power Consumption: With a quiescent current of just 1.2µA, the MAX6806UR23 is optimized for battery-powered and portable applications.
• Manual Reset Input: A debounced manual reset input is provided, allowing for a manual system reset whenever necessary.
• Reset Timeout: A minimum reset timeout of 140ms offers a reliable reset signal duration.
• Compact Package: Offered in a small SOT23-3 package, the MAX6806UR23 is suitable for space-constrained applications.

With its ability to operate over a wide temperature range of -40°C to +125°C, the MAX6806UR23 is versatile for various industrial and automotive applications where consistent performance is required regardless of environmental conditions.

Whether you're designing an embedded system, IoT device, or any other microprocessor-based product, the Maxim Integrated MAX6806UR23 provides a simple and effective solution for your power supply monitoring needs, ensuring your system operates reliably without the need for complex circuitry.
