Maxim Integrated MAX6817EUT-T Single/Dual, Low-Voltage, Low-Power µP Reset Circuits

The MAX6817EUT-T from Maxim Integrated is a compact, highly reliable single/dual low-voltage, low-power microprocessor (µP) reset circuit designed to monitor power supplies in digital systems. It provides a crucial safeguard for sensitive electronic equipment, ensuring that the system's microprocessor is reset to a known state during power-up, power-down, or brown-out conditions.

This particular device comes in a tiny 6-pin SOT-23 package, making it an ideal choice for space-constrained applications. The MAX6817EUT-T operates over a wide voltage range from 1.0V to 5.5V, which allows it to support a variety of low-voltage applications including portable devices, handheld electronics, and other battery-operated equipment.

One of the key features of the MAX6817EUT-T is its low power consumption, drawing a quiescent current of only 1µA, which is beneficial for extending the battery life in portable applications. Additionally, it offers an adjustable reset threshold voltage, which can be configured by external resistors, allowing designers to tailor the reset threshold to specific system requirements.

The device also includes a manual reset input that enables a system reset to be triggered with an external switch or logic signal. This feature provides an extra layer of control for system operators or maintenance personnel. Furthermore, the MAX6817EUT-T incorporates a debounce circuit that filters out any spurious noise on the manual reset input, ensuring reliable operation.

The reset output is available in both active-low and active-high configurations, which adds to the versatility of the device, making it compatible with a wide range of microprocessors and other digital ICs. The reset output is guaranteed to be in the correct state for VCC down to 1.0V, which assures proper system reset even during low-voltage conditions.

With its robust feature set and Maxim Integrated's reputation for high-quality electronic components, the MAX6817EUT-T is an excellent choice for designers looking to enhance the reliability and performance of their digital systems.
