MAX6314US44D2+T

Supervisors Overview

The MAX6314US44D2+T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors power supplies in microprocessor and digital systems with a fixed threshold voltage of 4.40V and an overvoltage threshold of 4.47V. The device features a bidirectional active-low reset output compatible with inputs like the 68HC11, along with a debounced manual reset input. It operates within a supply voltage range up to 5.5V, consumes 5µA of operating current, and provides a 200ms reset delay time. Accuracy is specified at 1.8%, and it functions reliably 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
• Integrated 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 voltage supervision
• Systems requiring bidirectional reset compatibility

Supervisors Procurement Notes

Verify the specific suffix D2 against official Analog Devices documentation to confirm package type and thermal characteristics. Ensure the component meets RoHS compliance requirements as indicated by the plus sign. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Supervisors Selection Notes

Select this component when a bidirectional reset interface is required for microprocessors such as the 68HC11. Choose based on the fixed 4.40V threshold and 200ms timeout duration. Consider the SOT-143-4 package for surface-mount assembly and verify that the 5.5V maximum supply voltage aligns with the target system design.

Supervisors Part Context

The MAX6314 belongs to the MAX6314 series of low-power CMOS microprocessor supervisory circuits. This family is designed to eliminate external components and adjustments while providing excellent circuit reliability. The device performs a single function: asserting a reset signal when the VCC supply voltage falls below a preset threshold or when the manual reset input is asserted.
