MAX6368HKA29+T

Overview

The MAX6368HKA29+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.9 V for monitoring single inputs. The device provides an active high, open-drain output with a reset delay time of 280 ms. It includes battery backup switching and chip enable gating capabilities but lacks manual reset or watchdog timer functions. Operating temperatures span from -40°C to +85°C, with a typical quiescent current of 15 µA.

Feature Summary

• Integrates battery backup switching functionality for seamless power transition management.
• Includes chip enable gating to control circuit operation states efficiently.
• Delivers active high open-drain reset output for reliable system supervision.

Applications

• Portable electronic devices requiring low-power voltage supervision
• Battery-operated systems needing backup power management
• Embedded controllers utilizing chip enable gating

Procurement Notes

Verify component authenticity through authorized distributors due to limited availability status. Confirm package integrity upon receipt as surface-mount components are sensitive to handling. Check datasheet revisions for any updates regarding electrical characteristics or pin configurations before finalizing design integration.

Selection Notes

Select this part when a fixed 2.9 V threshold is required for single-input monitoring. Consider the 15 µA quiescent current for battery life optimization. Ensure compatibility with active high open-drain logic levels in the target system design.
