Maxim Integrated MAX6806US23-C74445 Microprocessor Reset Circuit

The Maxim Integrated MAX6806US23-C74445 is a high-quality 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 in systems with a 2.3V power supply voltage. This device is particularly suitable for portable and battery-powered electronics due to its low power consumption and compact size.

The MAX6806US23-C74445 comes in a small SOT-143 package, making it an ideal choice for space-constrained applications. It features a factory-trimmed reset threshold voltage of 2.3V, ensuring that the microprocessor resets accurately whenever the supply voltage drops below this preset threshold. The reset output remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, providing ample time for the system to stabilize upon power-up.

One of the key features of this device is its ability to assert a reset signal if the supply voltage drops momentarily, which helps to protect the system from data corruption and ensures reliable operation. The MAX6806US23-C74445 also has a low supply current of 1.2µA, making it an energy-efficient choice for battery-operated devices. It is designed to operate over a wide temperature range of -40°C to +125°C, which makes it suitable for use in harsh environmental conditions.

Additional features include a debounced manual reset input, allowing the option for an external override, and an active-low push-pull reset output, which provides a direct interface to the microprocessor without the need for an external pull-up resistor. This product is designed with Maxim Integrated's commitment to high-quality and reliability, ensuring that it meets the rigorous demands of modern electronic systems.

Whether it's for consumer electronics, industrial controls, or automotive systems, the MAX6806US23-C74445 is an excellent choice for designers looking for a simple, efficient, and reliable solution to manage their system's power supply and reset functions.
