MAX6306UK30D3

Supervisors Overview

The MAX6306UK30D3+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range of up to 5.5V and features a fixed reset threshold of 3V with an overvoltage threshold of 3.045V. The device provides a manual reset input, an active low open-drain output, and a reset delay time of 1.4ms. It consumes 8µA of operating current and functions across a temperature range of 0°C to +70°C in a SOT-23-5 package.

Supervisors Feature Summary

• Monitors multiple power supply inputs to assert system reset if any supply falls outside programmed thresholds
• Immune to fast transients on monitored supplies to prevent false triggering
• Includes manual reset input for user-initiated system control

Supervisors Applications

• Portable computers
• Personal computer systems monitoring 5V and 3.3V rails
• Controllers and intelligent instruments
• Multivoltage embedded control systems

Supervisors Procurement Notes

Verify the specific suffix against official documentation, as variations like D3L or D1 may alter electrical characteristics such as reset delay or output type. Confirm RoHS compliance status and lead times directly with Analog Devices or authorized distributors, as availability for this specific part number may be restricted or limited.

Supervisors Selection Notes

Select this component when monitoring multiple voltage rails requires a single IC solution with factory-set thresholds. Ensure the required reset delay and output drive capability match the system design. Verify that the operating temperature range meets environmental requirements and that the SOT-23-5 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs from Maxim Integrated. These devices are engineered for portable applications due to low supply current and small package size. The series allows monitoring of various supply combinations, such as 3V/5V or 5V/12V, ensuring reliable system operation under varying power conditions.

Supervisors Replacement Considerations

Check for MAX6306 variants with different suffixes (e.g., D1, D2) which may offer different reset delays or accuracy levels. Verify pinout compatibility before substitution.
