MAX6365LKA29-T

Overview

The MAX6365LKA29+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, push-pull output with a reset delay time of 280 ms. It includes manual reset capability and battery backup switching functionality, while lacking a watchdog timer. Designed for surface-mount installation in an SOT-23-8 package, it supports chip-enable gating and consumes only 15 uA of operating current. The component functions reliably across a temperature range from -40 C to +85 C.

Feature Summary

• Integrates battery backup switching to maintain system integrity during power transitions.
• Provides manual reset control for user-initiated system recovery operations.
• Supports chip-enable gating to manage power consumption states effectively.

Applications

• Microprocessor reset circuits requiring low standby current
• Battery-powered systems needing backup power management
• Portable electronic devices with strict power constraints

Procurement Notes

Verify the exact suffix designation against official manufacturer documentation, as variations such as +T indicate specific tape-and-reel packaging configurations. Confirm RoHS compliance status through the latest datasheet revision. Ensure that the selected variant matches the required threshold voltage and package type for your specific design implementation. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a single monitored input with a precise 2.93 V threshold is required alongside manual reset functionality. Consider the SOT-23-8 package size for space-constrained layouts. Evaluate the 15 uA quiescent current against total system power budgets. Verify compatibility with the intended supply voltage range and operating temperature environment before finalizing the bill of materials.

Part Context
