Product Overview: MAX6319LHUK31A+

The MAX6319LHUK31A+ is a highly precise, low-power microprocessor (µP) supervisory circuit designed by Maxim Integrated to monitor power supplies in µP and digital systems. It provides a significant increase in system reliability and accuracy compared to separate ICs or discrete components. With its compact SOT23 package, it is an ideal solution for space-constrained applications.

Key Features

• Voltage Monitoring: This device offers a factory preset reset threshold voltage of 3.08V, ensuring reliable operation by monitoring the power supply voltage of the µP and asserting a reset if it drops below a safe level.
• Reset Timeout: It features a 140ms min reset timeout delay, which gives the system enough time to stabilize after a power-down or power-up event before the µP starts to operate.
• Low Power Consumption: Designed for power-sensitive applications, the MAX6319LHUK31A+ consumes very low power, with a typical supply current of only 1.2µA, making it ideal for battery-operated devices.
• Manual Reset Input: The device includes a manual reset input that allows the user to trigger a reset with an external pushbutton or logic signal, providing an additional layer of system control.
• Temperature Range: It operates over an extended temperature range from -40°C to +125°C, accommodating a wide range of environmental conditions.

Applications

Due to its robust feature set, the MAX6319LHUK31A+ is suitable for a variety of applications, including:

• Portable/Battery-Powered Equipment
• Computers and Controllers
• Embedded Systems
• Data Storage Equipment
• Medical Devices
