MAX6364LUT26

Overview

The MAX6364LUT26 is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single voltage input and provides an active-low, push-pull reset output. The device features a battery backup switch to maintain system integrity during power transitions. Key electrical parameters include a threshold voltage of 2.63V, a maximum supply voltage of 5.5V, and a reset delay time of 280ms. It operates within a temperature range of -40°C to +85°C and consumes only 15µA of supply current. The component is housed in a compact SOT-23-6 package, suitable for surface-mount applications requiring precise voltage supervision.

Feature Summary

• Monitors power-supply voltages with factory-set reset thresholds
• Includes a battery backup switch for seamless power transition management
• Provides an active-low, push-pull reset output signal
• Operates with ultra-low supply current consumption

Applications

• Microprocessor system power supervision
• Battery-powered electronic devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific lot traceability requirements before procurement. Ensure storage conditions adhere to moisture sensitivity level specifications to prevent package degradation. Cross-reference ordering suffixes to match exact threshold voltage and package variant requirements for your design.

Selection Notes

Select this component when a single-channel voltage monitor with battery backup functionality is required. Compare threshold voltage accuracy against system trip points to ensure reliable reset generation. Evaluate supply current constraints against battery life expectations. Consider the SOT-23-6 footprint compatibility with existing PCB layouts. Verify operating temperature range alignment with environmental conditions.

Part Context

This part belongs to the MAX6363/MAX6364 series of low-power µP reset circuits. These devices are designed to provide reliable supervision for digital systems. The series offers various threshold voltages and timeout delays to accommodate different processor requirements. The MAX6364 variant specifically includes the battery backup feature, distinguishing it from standard reset supervisors.

Replacement Considerations

Check MAX6363LUT26+T for identical electrical characteristics without battery backup. Verify MAX6364LUT46+T for alternative threshold voltage options within the same package. Consult official substitution lists for updated revisions ensuring pinout and functional compatibility.
