Maxim Integrated MAX6866UK26D3S+ Microprocessor Reset Circuit

The Maxim Integrated MAX6866UK26D3S+ is a highly reliable 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 2.63V voltage threshold. This device is particularly suitable for portable, battery-operated applications due to its low power consumption and small footprint.

This supervisory circuit ensures that the microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. The reset output of the MAX6866UK26D3S+ remains asserted for a minimum of 140ms after V_CC has risen above the reset voltage threshold, providing ample time for the system to stabilize.

The compact SOT23-5 package of the MAX6866UK26D3S+ makes it an ideal choice for space-constrained applications. Its operating temperature range of -40°C to +85°C ensures that the device can perform reliably in a wide range of environments and applications.

By providing a push-pull active-low reset output, the MAX6866UK26D3S+ can interface directly with many microprocessors and microcontrollers without requiring additional components. Its ability to ignore short V_CC transients helps prevent unnecessary resets, thereby improving system stability and performance.

Overall, the Maxim Integrated MAX6866UK26D3S+ is a smart choice for designers looking for a simple, cost-effective solution to enhance system reliability and performance in microprocessor-based systems. Its precise monitoring capabilities and robust feature set make it a versatile component for a wide array of applications.
