MAX6897AALT+T

Supervisors Overview

The MAX6897AALT+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.5 V to 5.5 V and features an adjustable overvoltage threshold with a minimum detectable level of 500 mV. The device provides a high-active, open-drain reset output and includes a chip enable signal for power management. It supports a reset delay time of 190 ms and maintains an accuracy of 1.8%. Designed for surface mount installation, it is housed in a compact 6-µDFN (1.5x1) package. The component functions reliably across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Features an adjustable overvoltage threshold allowing flexible monitoring of various supply rails.
• Includes a chip enable pin to control device operation and reduce power consumption.
• Provides a high-active reset output with configurable timing characteristics.

Supervisors Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-powered systems needing efficient power management
• Industrial equipment operating in extreme temperature environments

Supervisors Procurement Notes

Verify the specific suffix and tape-and-reel packaging details against the manufacturer's official documentation before ordering. Confirm that the 6-µDFN footprint matches your PCB layout requirements. Ensure compatibility with your system's voltage levels and temperature specifications. Check for any recent lifecycle status updates or alternative recommendations from Analog Devices. Validate RoHS compliance and environmental certifications as required by your project standards.

Supervisors Selection Notes

Select this component when a small form factor supervisor with adjustable thresholds is required. Consider the open-drain output configuration for compatibility with different logic levels. Evaluate the 1.5 V minimum operating voltage against your lowest expected supply rail. Assess the need for chip enable functionality to optimize standby current. Compare the 190 ms reset delay against your system's startup timing constraints.
