MAX6366PKA23

Overview

The MAX6366PKA23 is a low-power microprocessor supervisory circuit manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 2.32 V with an overvoltage threshold of 2.38 V. The device provides an active low, open-drain output and includes a built-in watchdog timer. It offers a reset delay time of 280 ms and supports battery backup switching. The component draws a working supply current of 15 uA and dissipates up to 700 mW. It is housed in an SOT-23-8 package and functions across a temperature range from -40 C to +85 C.

Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports battery backup switching for continuous operation during power transitions
• Includes chip-enable gating functionality for power management control

Applications

• Microprocessor system supervision
• Battery-powered electronic devices requiring low standby current
• Systems needing automatic reset upon power failure or brown-out conditions

Procurement Notes

Verify the exact part number suffix and manufacturer documentation before procurement, as availability may be limited due to lifecycle status. Confirm that the specific threshold voltage and package variant match your design requirements. Check for obsolescence notices or recommended new replacements directly from Analog Devices official channels to ensure long-term supply chain stability.

Selection Notes

Select this component when a dedicated supervisor with integrated watchdog and battery backup is required. Ensure the 2.32 V threshold aligns with the monitored rail voltage. Consider the SOT-23-8 footprint constraints and the active low open-drain output compatibility with the target logic levels. Verify thermal dissipation limits against the expected operating environment.
