MAX6306UK30D3-T

Supervisors Overview

The MAX6306UK30D3-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features a 5-Pin SOT-23 package and operates with an 8µA supply current. The device monitors two inputs, providing an active low open-drain reset output with a manual reset input. It has a fixed threshold voltage of 3V and a reset delay time of 1.4 ms. The maximum supply voltage is 5.5 V, and it includes overvoltage detection at 2.538 V.

Supervisors Feature Summary

• Monitors more than one power supply and asserts system reset if any monitored supply falls outside the programmed threshold
• Specifically designed to ignore fast transients on any monitored supply
• Features a manual reset input for external control

Supervisors Applications

• Portable computers
• Computers
• Controllers
• Intelligent instruments
• Multivoltage systems

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free specifications against the official datasheet. Ensure the part number suffix matches the required threshold voltage and package variant. Check for obsolescence notices or limited availability warnings from Analog Devices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when monitoring multiple voltage rails in portable or battery-powered equipment. The low supply current suits energy-constrained applications. Verify that the factory-set 3V threshold aligns with the target supply rail requirements. Ensure the open-drain output configuration fits the system logic interface constraints.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of 5-pin multiple-input programmable reset ICs. These devices are engineered for personal computer systems and portable applications requiring reliable power supervision. The series offers precision factory-set thresholds and immunity to short transients, ensuring stable operation in dynamic power environments.

Supervisors Replacement Considerations

Consider MAX6306UK30D3+T as a potential alternative. Verify pinout compatibility and electrical parameter alignment before substitution.
