MAX6318LHUK26AY-T

Supervisors Overview

The MAX6318LHUK26AY-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5V and features a fixed reset threshold voltage of 2.6V. The device is housed in a compact SOT-23-5 surface-mount package, suitable for space-constrained designs. It provides manual reset functionality and supports active high, active low, or push-pull output configurations. The component is rated for an extended industrial temperature range from -40°C to +125°C, ensuring reliable operation in demanding environments.

Supervisors Feature Summary

• Integrates manual reset input capability for system control
• Offers flexible output drive options including push-pull and open-drain
• Designed for monitoring power supplies and processor activity

Supervisors Applications

• Microprocessor power supply supervision
• Digital system reset management
• Portable electronic devices requiring low standby current

Supervisors Procurement Notes

Verify the specific suffix 'AY' against official datasheets to confirm lead time and availability status, as distribution channels may list varying stock levels. Confirm RoHS compliance details directly with the manufacturer or authorized distributors, as historical data indicates potential variations between leaded and lead-free versions for this specific part number variant.

Supervisors Selection Notes

Select this component when a fixed 2.6V threshold is required for single-supply monitoring. Ensure the application does not require a watchdog timer, as this specific variant lacks that feature. Verify that the SOT-23-5 package fits the PCB layout constraints and that the operating temperature range meets the environmental requirements of the target system.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices are designed to monitor power supplies and microprocessor activity in digital systems. The family offers various combinations of reset outputs and features such as watchdog timers and manual resets, providing a versatile solution for system protection and reset generation.

Supervisors Replacement Considerations

Cross-reference with other MAX6318 variants sharing the same SOT-23-5 package and 2.6V threshold. Verify functional compatibility regarding output type and manual reset presence before substitution.
