MAX6318LHUK29CY-T

Supervisors Overview

The MAX6318LHUK29CY-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors power supplies in digital systems and features a manual reset input. The device operates within a supply voltage range of up to 5.5V and includes a fixed reset threshold voltage of 2.9V. It utilizes an SOT-23-5 surface-mount package and supports active high, active low, and push-pull output configurations. The circuit ensures system reliability through precise voltage monitoring and manual intervention capabilities.

Supervisors Feature Summary

• Integrates manual reset functionality for direct user control over system state
• Provides factory-trimmed reset threshold voltages for accurate power supervision
• Supports multiple output types including push-pull and open-drain configurations

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Digital system reset generation with manual override capability
• Voltage supervision for battery-powered devices requiring low quiescent current

Supervisors Procurement Notes

Verify the exact suffix 'CY' against official datasheets to confirm temperature grade and packaging specifications. Confirm availability status as distribution channels may list limited stock or obsolete status. Ensure the ordering part number matches the specific threshold voltage variant required for the design. Cross-reference manufacturer documentation for any recent lifecycle changes or recommended replacements.

Supervisors Selection Notes

Select this component when a fixed 2.9V reset threshold is required alongside manual reset control. Consider the SOT-23-5 package size for space-constrained designs. Evaluate the operating temperature range and output drive requirements against system specifications. Compare quiescent current consumption if battery life is a critical design constraint.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin microprocessor supervisory circuits. These devices are designed to monitor power supplies and processor activity. The family offers various combinations of reset outputs and watchdog features. The MAX6318 specifically provides manual reset input support without a watchdog timer function.

Supervisors Replacement Considerations

Check the MAX6319 series for similar functionality with different threshold options. Verify compatibility with MAX6316 or MAX6320 variants if pinout and feature sets align. Consult official substitution guides for updated components within the same product family.
