MAX6318MHUK46CY-T

Supervisors Overview

The MAX6318MHUK46CY-T is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, manufactured by Analog Devices Inc./Maxim Integrated. It monitors power supplies and processor activity in digital systems. The device features a fixed reset threshold voltage of 4.6 V and operates within a supply voltage range up to 5.5 V. It is housed in a SOT-23-5 surface-mount package and supports an operating temperature range from -40°C to +125°C. The circuit includes manual reset functionality and provides push-pull or open-drain reset outputs.

Supervisors Feature Summary

• Monitors power supply voltages and microprocessor activity for system reliability
• Includes manual reset input for user-initiated system resets
• Offers flexible reset output configurations including push-pull and open-drain options

Supervisors Applications

• Digital system power supply monitoring
• Microprocessor activity supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the exact suffix 'CY' against official Maxim Integrated documentation to confirm specific tape-and-reel packaging or temperature grade variations. Confirm RoHS compliance status as indicated in current datasheets. Check production status directly with the manufacturer due to potential limited availability or obsolescence notices associated with this component series.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required for single-supply monitoring. Ensure the application utilizes the available reset output types (push-pull/open-drain) compatible with the target logic levels. Verify that the manual reset feature meets system requirements and that the SOT-23-5 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices are designed to provide reliable reset signals for digital systems. The family offers various factory-trimmed threshold voltages and combinations of watchdog timers, manual resets, and output types to suit different microprocessor architectures.

Supervisors Replacement Considerations

Consult the MAX6316–MAX6322 selector guide for alternatives with matching 4.6 V thresholds. Consider parts like MAX6318MHUK46BZ+T if package or reel differences exist. Verify functional equivalence regarding reset delay and output configuration before substitution.
