MAX6313UK46D3

Supervisors Overview

The MAX6313UK46D3 is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range up to 5.5V and features a factory-programmed reset threshold of 4.6V. The device provides an active-high, push-pull output with a reset delay time of 200ms. It monitors two inputs and includes manual reset functionality. The component draws 8µA of operating supply current and is housed in a compact SOT-23-5 package suitable for surface mount applications.

Supervisors Feature Summary

• Monitors multiple power supplies and asserts system reset if any monitored supply falls outside the programmed threshold
• Features an active-high, push-pull output type for direct interface compatibility
• Includes a manual reset input for external control of the reset state
• Designed to ignore fast transients on monitored supplies to prevent false resets

Supervisors Applications

• Portable computers requiring dual voltage monitoring
• Personal computer systems monitoring 5V and 3.3V rails
• Battery-powered equipment needing low supply current supervision
• Multivoltage embedded control systems

Supervisors Procurement Notes

Verify the specific suffix D3 against the manufacturer's datasheet to confirm the exact reset threshold voltage and timeout delay characteristics. Ensure the active-high output configuration matches the target system logic requirements. Confirm RoHS compliance status for the specific manufacturing batch prior to integration into final assemblies.

Supervisors Selection Notes

Select this component when an active-high output is required instead of the standard active-low variant. Verify that the 200ms reset delay meets the system startup timing constraints. Ensure the 4.6V threshold aligns with the specific power rail being monitored. Check compatibility with the available SOT-23-5 footprint during PCB layout design.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs manufactured by Analog Devices Inc./Maxim Integrated. The series is engineered for portable applications due to low supply current consumption and small package size. These devices are specifically designed to monitor more than one power supply and assert a system reset if any monitored supply falls outside the programmed threshold.

Supervisors Replacement Considerations

Cross-reference with other MAX6313 variants such as MAX6313UK28D3-T or MAX6313UK32D3-T if different reset thresholds are needed. Verify that alternative parts maintain the same active-high, push-pull output configuration and SOT-23-5 package to ensure pinout compatibility.
