MAX6318LHUK26CY+

Supervisors Overview

The MAX6318LHUK26CY+ is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supplies in digital systems with a fixed reset threshold voltage of 2.575 V. The device operates within a supply voltage range up to 5.5 V and features a push-pull active-low reset output. It includes manual reset functionality but lacks a watchdog timer or battery backup switch. The component is housed in a SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Monitors power supply voltages for microprocessor activity in digital systems
• Provides manual reset input capability for system control
• Features a push-pull active-low reset output signal

Supervisors Applications

• Microprocessor power supply monitoring
• Digital system supervision
• Manual reset circuit implementation

Supervisors Procurement Notes

Verify the specific suffix CY+ against official Analog Devices documentation to confirm package type and temperature grade. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Check current availability as distribution status may vary. Ensure the sourcing channel provides valid traceability for this specific part number.

Supervisors Selection Notes

Select this component when a fixed 2.575 V threshold is required for single-supervision applications. Choose the SOT-23-5 package for space-constrained designs. Verify that the absence of a watchdog timer meets system requirements. Ensure the operating temperature range aligns with the deployment environment.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices offer various combinations of reset outputs and features like watchdog timers and manual resets. The MAX6318 variant specifically excludes the watchdog timer found in other family members, focusing on basic supervision and manual reset capabilities.

Supervisors Replacement Considerations

Other MAX631x variants with different threshold voltages or additional features like watchdog timers may serve as functional substitutes if electrical parameters align. Verify pin compatibility and output configuration before substitution.
