MAX6314US25D1+T

Supervisors Overview

The MAX6314US25D1+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 processors like the 68HC11 and includes a debounced manual reset input. The device operates within a supply voltage range of 1V to 5.5V, with a specific threshold voltage of 2.50V for this variant. It provides a fixed reset timeout period of 200ms and maintains an operating current of 5µA. The component is housed in a compact SOT-143-4 surface-mount package.

Supervisors Feature Summary

• Bidirectional RESET output enables direct connection to microprocessors with bidirectional reset inputs, such as the 68HC11 family.

Supervisors Applications

• Microprocessor (µP) system power supply monitoring
• Digital system voltage supervision
• Manual reset circuit integration

Supervisors Procurement Notes

Verify the exact threshold voltage suffix against the official datasheet, as the '25' designation typically indicates a 2.50V threshold. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the SOT-143-4 package matches your PCB footprint requirements. Cross-reference the part number with Analog Devices or Maxim Integrated official sources to confirm availability and revision history before finalizing procurement.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for compatibility with specific microcontrollers like the 68HC11. It is suitable for applications needing a manual reset input alongside automatic undervoltage detection. Consider the 5µA quiescent current for low-power designs. Verify that the 2.50V threshold aligns with the target system's logic levels and supply rail characteristics.

Supervisors Part Context

This part belongs to the MAX6314 series of microprocessor supervisory circuits manufactured by Analog Devices (Maxim Integrated). The series is characterized by low power consumption and integrated manual reset functionality. The US25D1 suffix denotes the specific threshold voltage, package type, and temperature grade within the broader product line.

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, facilitating seamless integration without additional level-shifting components.

Does the MAX6314US25D1+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.
