MAX6365HKA46+T

Overview

The MAX6365HKA46+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It features a single monitored voltage input with a fixed threshold of 4.63V. The device provides a high-active reset output with a minimum timeout of 150ms. It includes a battery backup switch and chip-enable gating functionality. Operating within a temperature range of -40°C to +85°C, it utilizes an SOT-23-8 surface-mount package.

Feature Summary

• Integrates battery backup switching for seamless power transition between main supply and backup sources.
• Includes chip-enable gating to allow system control over the supervisor's operational state.
• Delivers a high-active push-pull or open-drain/collection reset signal upon undervoltage detection.

Applications

• Microprocessor power supply monitoring in embedded systems
• Battery-powered devices requiring backup power management
• Industrial control units needing reliable voltage supervision

Procurement Notes

Verify component authenticity through authorized distributors as this part may be discontinued. Confirm package integrity and pin alignment against the SOT-23-8 specification before integration. Check for RoHS compliance documentation if required by your manufacturing standards. Ensure the specific suffix matches your design requirements regarding output configuration and threshold voltage.

Selection Notes

Select this component when a fixed 4.63V threshold is appropriate for the target rail. Consider the high-active reset polarity compatibility with the downstream logic family. Evaluate the 150ms minimum timeout duration against the microprocessor startup requirements. Verify that the SOT-23-8 footprint fits the available PCB space constraints.
