MAX6368PKA29+T

Overview

The MAX6368PKA29+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 0 V to 5.5 V and features an adjustable overvoltage threshold. The device monitors a single input channel with a fixed reset delay time of 280 ms. It utilizes an active-low, open-drain output type and includes a battery backup switch for seamless power transitions. The component supports chip enable gating and consumes a typical operating supply current of 15 uA. It is housed in an SOT-23-8 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates battery backup functionality to maintain system state during power transitions
• Features chip-enable gating for precise control over monitoring operations
• Provides open-drain output signaling for flexible logic interface compatibility

Applications

• Embedded systems requiring reliable power supervision
• Battery-powered devices needing backup switching capabilities

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm electrical characteristics and packaging configuration. Ensure that the requested variant matches the required threshold voltage and output polarity specifications for your design. Confirm availability status through authorized distributors as supply constraints may apply to this component series.

Selection Notes

Select this component when a low-power supervisor with integrated battery backup is required for single-rail monitoring applications. Consider the 280 ms reset delay and open-drain output structure for timing and interface compatibility. Evaluate the 15 uA quiescent current consumption against system power budgets and verify that the SOT-23-8 package fits the mechanical constraints.
