MAX6318LHUK27CY+

Supervisors Overview

The MAX6318LHUK27CY+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and features a fixed reset threshold voltage of 2.7V with an accuracy of 1.5%. The device provides a push-pull active-low reset output and includes a manual reset input. It supports a watchdog timer with selectable timeout periods and offers power-on reset delays ranging from 1ms to 1.12s. The component functions reliably across an extended temperature range of -40°C to +125°C and is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Monitors power supply voltage and microprocessor activity for system reliability
• Integrates a watchdog timer with manual reset capability for fault recovery
• Provides factory-trimmed reset thresholds with high precision accuracy
• Supports multiple reset output configurations including push-pull and open-drain

Supervisors Applications

• Watchdog timer implementation for digital logic protection
• Manual reset input integration for user-initiated system recovery
• Battery-powered devices requiring low standby current monitoring

Supervisors Procurement Notes

Verify the specific suffix 'CY' against official manufacturer documentation to confirm lead time, moisture sensitivity level, and RoHS compliance status. Ensure the ordering part number matches the exact threshold voltage and package variant required for your design. Cross-reference the datasheet revision history for any updates to electrical characteristics or recommended operating conditions before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 2.7V threshold is required for precise voltage monitoring. Consider the SOT-23-5 package for space-constrained designs. Evaluate the need for watchdog functionality versus simpler reset-only circuits. Confirm that the 1.5% threshold accuracy meets the system's noise margin requirements. Verify compatibility with the target microprocessor's reset signal polarity and timing constraints.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin microprocessor supervisory circuits. The family offers various combinations of reset outputs, watchdog timers, and manual resets. Different suffixes indicate variations in threshold voltage, package type, and temperature range. This specific model targets applications needing a 2.7V threshold with integrated watchdog capabilities in a small form factor.
