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

The MAX6817EUT+T from Maxim Integrated is a compact, high-precision microprocessor (µP) supervisory circuit designed to monitor power supplies in microprocessor and digital systems. It provides a significant level of system reliability and accuracy essential for modern electronics. This device is particularly suitable for battery-powered applications due to its low power consumption and small footprint.

The MAX6817EUT+T operates over a wide voltage range from 1.0V to 5.5V, making it versatile for various applications, including portable devices, computers, controllers, and intelligent instruments. Its primary function is to assert a reset signal whenever the VCC supply voltage falls below its reset threshold level, ensuring that the µP starts in a known state. The reset output remains asserted for a preset timeout period after VCC has risen above the reset threshold, providing the system with enough time to stabilize.

This device is available in a 6-pin SOT-23 package, which is ideal for space-constrained applications. The SOT-23 package is not only small but also provides excellent thermal performance, ensuring the device operates within its specified temperature range of -40°C to +85°C.

Key features of the MAX6817EUT+T include:

• Low supply current of 1.6µA, which is critical for extending battery life in portable applications.
• Factory-trimmed reset threshold voltages for high accuracy.
• Immunity to short VCC transients, ensuring reliable operation under fluctuating power conditions.
• Debounced manual reset input, allowing for a controlled and predictable reset initiation.
• Open-drain reset output, which provides flexibility in interfacing with different logic levels.

With its robust feature set, the MAX6817EUT+T is an excellent choice for designers looking to enhance system stability and reliability in their digital and microprocessor-based systems. Maxim Integrated's commitment to quality ensures that this reset circuit will maintain performance over a wide range of environmental conditions and use cases.
