The MAX6319LHEUK29C+T is a robust and precise microprocessor (μP) supervisory circuit from Maxim Integrated, designed to improve the reliability and system stability of digital devices. This component is specifically engineered to monitor power supplies and microprocessor activity, ensuring that systems operate within their desired parameters.

Key Features

• Voltage Monitoring: The device offers precise voltage monitoring, typically at 2.93V, ensuring that the system is protected from undervoltage conditions that could lead to erratic operation or data loss.
• Reset Output: It provides an active-low reset output, which remains asserted for a minimum of 140ms after V<sub>CC has risen above the reset threshold, allowing sufficient time for the μP and other circuits to stabilize.
• Low Power Consumption: With a low supply current of only 1.2μA, the MAX6319LHEUK29C+T is an energy-efficient solution, contributing to the overall power efficiency of the system it is integrated into.
• High Accuracy: This supervisory circuit features a reset threshold accuracy of ±1.5%, providing reliable operation without false triggering.
• Temperature Range: It is operational over the extended industrial temperature range of -40°C to +125°C, making it suitable for use in harsh environments.
• Package: The device comes in a compact SOT-23 package, which is ideal for space-constrained applications.
