MAX6366PKA29-T

Overview

The MAX6366PKA29-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 of up to 5.5 V and features a fixed threshold voltage of 2.93 V for monitoring input lines. The device provides an active-low, open-drain reset output with a typical delay time of 280 ms. Key functional blocks include a watchdog timer, battery backup switch, and chip-enable gating. It draws a maximum operating supply current of 15 uA and functions reliably across an industrial temperature range from -40°C to +85°C. The component is housed in an SOT-23-8 surface-mount package.

Feature Summary

• Integrates a watchdog timer for system fault recovery
• Includes a battery backup switch for seamless power transitions
• Supports chip-enable gating for power management control

Applications

• Portable electronic devices requiring low standby current
• Battery-powered systems needing voltage supervision
• Industrial control units operating in harsh environments

Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations may exist between tape-and-reel configurations and specific lot codes. Confirm RoHS compliance status through the latest datasheet revision. Ensure compatibility with existing PCB footprints for the SOT-23-8 package before finalizing procurement plans.

Selection Notes

Select this component when a fixed 2.93 V threshold is required for precise voltage monitoring. The integrated watchdog and battery backup features reduce external component count compared to discrete solutions. Consider the 15 uA quiescent current for strict energy budget constraints in portable applications.

Part Context

This part belongs to the MAX6366P series of low-power supervisors. It shares architectural similarities with other variants in the family but differs in threshold voltage settings. The MAX6366P series is designed for applications demanding high reliability and minimal power consumption in compact form factors.

Replacement Considerations

Consult official substitution guides for equivalent parts with matching threshold voltages and package types. Verify pinout compatibility and electrical specifications before replacing.
