Product Overview: MAX6456UT29S from Analog Devices Inc.

The MAX6456UT29S is a high-precision, low-power microprocessor (µP) supervisory circuit designed by Analog Devices Inc. to monitor single power-supply voltages. This component is part of a family of devices that are essential for reliable system operation by providing supervisory functions that are critical in ensuring stable and secure operation of microprocessors and digital systems.

Key Features

• Voltage Monitoring: The device is specifically designed to monitor a +2.9V power supply, ensuring that the system voltage remains within acceptable thresholds for reliable operation.
• Reset Output: It features an active-low reset output that provides a clean reset signal to the connected µP during power-up, power-down, or brown-out conditions. The reset signal remains asserted for a minimum timeout period after VCC has risen above the reset threshold, ensuring the µP restarts properly.
• Low Power Consumption: With a quiescent current of just 1.2µA at +3.6V, the MAX6456UT29S is ideal for battery-powered and portable applications where power conservation is paramount.
• High Accuracy: The device offers a high threshold accuracy of ±1.5% over the extended temperature range, which is crucial for systems that require precise voltage monitoring.
• Manual Reset: A manual reset input is provided, allowing for an external signal to trigger a system reset, offering additional system control and debugging capabilities.
• Compact Package: The MAX6456UT29S comes in a small, 6-pin SOT23 package, making it suitable for space-constrained applications.
