MAX6366LKA26+T

Overview

The MAX6366LKA26+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a fixed threshold of 2.63 V. The device provides an active-low reset signal with a minimum timeout of 150 ms and a typical delay of 280 ms. It utilizes a push-pull, totem-pole output configuration in an SOT-23-8 package. The component supports battery backup switching and chip-enable gating, functioning independently of downstream regulation stages while monitoring the primary supply rail across temperatures from -40°C to 85°C.

Feature Summary

• Integrates battery backup switching and chip-enable gating for seamless power management
• Monitors primary supply rails independently of downstream LDO or regulator stages
• Provides active-low reset signals with defined timeout characteristics

Applications

• Microprocessor system supervision
• Battery-backed power systems
• Embedded controller reset circuits

Procurement Notes

Verify the exact suffix (+T) indicates tape-and-reel packaging when sourcing. Confirm the manufacturer designation matches Analog Devices Inc. or Maxim Integrated as per current corporate structure. Ensure the part number aligns with RoHS compliance requirements if specified for your assembly process. Cross-reference the SOT-23-8 footprint dimensions against your PCB design library to guarantee mechanical compatibility before finalizing procurement orders.

Selection Notes

Select this component when a fixed 2.63 V threshold is required for low-voltage digital logic supervision. The integrated battery backup feature makes it suitable for systems requiring uninterrupted operation during main power loss. Consider the SOT-23-8 package size constraints and the specific reset timeout requirements of your target microcontroller. Verify that the push-pull output capability meets the drive requirements of the connected enable pins without additional buffering.
