MAX6314US46D2+T

Supervisors Overview

The MAX6314US46D2+T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a bidirectional RESET output compatible with microprocessors like the 68HC11 and includes a debounced manual reset input. The device operates within a supply voltage range up to 5.5 V, with a threshold voltage of 4.63 V and an accuracy of 1.8%. It draws 5 uA of operating current and provides a reset timeout period of 200 ms. The component functions in temperatures from -40°C to +85°C and is housed in a SOT-143 package.

Supervisors Feature Summary

• Bidirectional RESET output for direct connection to microprocessors with bidirectional inputs
• Debounced manual reset input for user-initiated system resets
• Low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system supervision
• Systems requiring manual reset functionality

Supervisors Procurement Notes

Verify the specific suffix D2 against the manufacturer's official part numbering guide to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status as indicated by the plus sign in the part number. Check current availability through authorized distributors, as stock levels may vary. Ensure the SOT-143 package footprint matches your PCB design requirements before ordering.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for compatibility with legacy or specific microprocessor architectures. It is suitable for designs needing a fixed 4.63 V threshold with high accuracy. Consider the 200 ms timeout duration to ensure it meets the minimum power-up time requirements of the target system. Verify that the 5 uA current draw aligns with the system's power budget constraints.

Supervisors Part Context

This part belongs to the MAX6314 series of supervisory circuits from Analog Devices/Maxim Integrated. The series is characterized by low power consumption and integrated manual reset capabilities. The US26/D3 suffix variants indicate different threshold voltages and packages within the same functional family. This specific model targets applications requiring precise voltage monitoring with bidirectional signal handling.

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 level-shifting components.

Does the MAX6314US46D2+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 manual reset capability.
