The MAX6717UKSFD2 is a highly reliable, precision dual/triple-voltage microprocessor (µP) supervisory circuit designed by Maxim Integrated 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 multiple supply voltages.

This supervisory circuit ensures that the microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. The integrated reset function guarantees that the µP reset input starts in the active state after power-up and remains active until the supply voltage reaches a stable condition above the reset threshold. The MAX6717UKSFD2 continues to monitor the supply voltage and keeps the reset active if the supply voltage drops below the preset threshold, ensuring that the processor is reset properly during a brown-out condition.

The device features a factory-trimmed reset threshold voltage and a built-in manual reset capability. The reset output is available in either a push-pull or open-drain configuration, which enhances the versatility of this supervisory circuit in various applications. The MAX6717UKSFD2 supports a wide operating voltage range, making it suitable for monitoring 3V, 3.3V, and 5V powered circuits.

Packaged in a compact SOT-23 form factor, the MAX6717UKSFD2 is optimized for space-constrained applications. It is an ideal choice for portable devices, computers, controllers, and intelligent instruments, where maintaining the correct operation of the microprocessor is critical. The low supply current makes it suitable for battery-operated equipment.

In summary, the Maxim Integrated MAX6717UKSFD2 is a versatile, reliable, and easy-to-use µP supervisory circuit that provides a robust solution for system monitoring. Its precision, compact size, and integration features make it an excellent choice for designers looking to enhance system stability and reduce the overall component count.
