MAX6314US30D1-T

Supervisors Overview

The MAX6314US30D1-T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in µP and digital systems. It features a bidirectional RESET output compatible with inputs like the 68HC11. The device monitors a single input with a threshold voltage of 3.0V and an overvoltage threshold of 3.07V. It operates within a supply voltage range up to 5.5V, consumes 5µA of supply current, and provides a reset delay time of 200ms. The component supports manual reset functionality without a watchdog timer or battery backup switch, operating between -40°C and +85°C.

Supervisors Feature Summary

• Bidirectional reset output for direct connection to microprocessors with bidirectional reset inputs
• Low-power CMOS design consuming minimal supply current
• Integrated debounced manual reset input
• Eliminates need for external components and adjustments

Supervisors Applications

• Microprocessor (µP) system power supply monitoring
• Digital system voltage supervision
• Systems requiring compatibility with 68HC11 bidirectional reset inputs

Supervisors Procurement Notes

Verify the specific suffix D1 against official Analog Devices documentation to confirm the exact threshold voltage and package variant, as suffixes define electrical characteristics. Confirm RoHS compliance status for the specific revision. Ensure the source document explicitly lists this part number to avoid confusion with similar MAX6314 variants that may have different thresholds or packages.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for direct coupling to specific microprocessor architectures. It is suitable for applications needing a fixed 3.0V threshold with a 200ms timeout. Consider the SOT-143-4 package constraints and the absence of watchdog or battery backup features when designing the power management strategy.

Supervisors Part Context

This part belongs to the MAX6314 series of microprocessor supervisory circuits from Analog Devices/Maxim Integrated. The series focuses on providing reliable reset signals for digital systems while minimizing external component count. The US30 designation indicates a specific factory-set threshold voltage within the product family.

Supervisors FAQ

What is the function of the bidirectional output?

The bidirectional output allows the MAX6314 to be directly connected to microprocessors that feature bidirectional reset inputs, such as the 68HC11, simplifying the interface design.

Does the MAX6314US30D1-T include a watchdog timer?

No, the MAX6314US30D1-T does not include a watchdog timer; it functions solely as a voltage supervisor with manual reset capability.
