MAX6364PUT23+

Overview

The MAX6364PUT23+ 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 reset threshold voltage of 2.38 V. The device provides an active-low, open-drain output with a standard reset delay time of 280 ms. Designed for surface-mount applications, it utilizes a SOT-23-6 package. The circuit draws a typical operating supply current of 15 uA, ensuring minimal power consumption during standby or active monitoring phases.

Feature Summary

• Monitors single power supply input for voltage integrity
• Generates system reset signal upon undervoltage condition
• Includes battery backup switch functionality for data retention

Applications

• Microprocessor (MPU) supervisor circuits
• Battery-powered embedded systems requiring voltage monitoring
• Portable electronic devices with limited power budgets

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks in the passive component market. Confirm RoHS compliance status and lead-free certification prior to integration. Check production lifecycle status as availability may be restricted or discontinued. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage before soldering.

Selection Notes

Select this part when a fixed 2.38 V threshold is required for low-voltage logic families. The open-drain output allows flexible interfacing with various logic levels via pull-up resistors. Consider the 280 ms delay duration against system startup timing requirements. Evaluate the 15 uA quiescent current impact on overall battery life for portable applications compared to higher-current alternatives.

Part Context

This component belongs to the MAX636x series of microprocessor supervisory circuits designed for reliable power management. It complements other variants in the family that offer different threshold voltages or output configurations. The series is engineered for industrial and commercial temperature ranges, providing robust performance in digital systems where stable power delivery is critical for operational integrity.

Replacement Considerations

Consult official cross-reference guides for direct pin-compatible substitutes with identical electrical characteristics. Verify that any alternative maintains the same 2.38 V threshold and open-drain output structure. Ensure thermal and mechanical specifications match the SOT-23-6 footprint to avoid PCB redesign.
