MAX6314US47D2+T

Supervisors Overview

The MAX6314US47D2+T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a fixed reset threshold voltage of 4.7V and an active-low, bidirectional RESET output compatible with microprocessors like the 68HC11. The device includes a debounced manual reset input and operates within a supply voltage range up to 5.5V. It provides a typical reset timeout period of 280ms after the supply voltage rises above the threshold. The component is available in a compact SOT-143-4 surface-mount package and supports operation across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs, such as the 68HC11 family.
• Integrated debounced manual reset input allows for user-initiated system resets without external components.
• Low quiescent current consumption supports battery-powered applications while maintaining reliable voltage supervision.

Supervisors Applications

• Microprocessor (µP) reset circuits for embedded systems
• Digital system power supply monitoring
• Battery-operated electronic devices requiring voltage supervision

Supervisors Procurement Notes

Verify the specific suffix D2 against official Analog Devices documentation to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status and lead-free designation via the manufacturer's datasheet. Check current availability through authorized distributors as supply status may vary. Ensure the ordering part number matches the required electrical specifications for your design.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for compatibility with legacy or specific microprocessor architectures. The fixed 4.7V threshold suits systems operating near 5V logic levels. Consider the SOT-143-4 package size for space-constrained PCB layouts. Verify that the 280ms timeout meets the startup requirements of the target processor.

Supervisors FAQ

What is the function of the bidirectional RESET output?

The bidirectional RESET output allows the MAX6314 to be directly connected to microprocessors with bidirectional reset pins, such as the 68HC11, eliminating the need for additional interface components.

Does the MAX6314US47D2+T include a watchdog timer?

No, the MAX6314 series does not include a built-in watchdog timer; it functions solely as a voltage supervisor with a manual reset input.
