MAX6312UK46D3+

Supervisors Overview

The MAX6312UK46D3+T is a CMOS microprocessor supervisory circuit designed to monitor power supplies. It operates within a supply voltage range up to 5.5V and features a factory-programmed reset threshold of 4.63V. The device provides an active-low, open-drain output with a manual reset input. It consumes only 8µA of supply current and is housed in a compact SOT-23-5 package suitable for portable applications.

Supervisors Feature Summary

• Monitors multiple power supplies and asserts system reset if any fall outside programmed thresholds
• Immune to short transients on monitored supplies
• Guaranteed RESET valid down to VCC = 1V

Supervisors Applications

• Monitoring 5V and 3.3V supplies in personal computer systems
• Portable electronic applications requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation. The provided model lacks the trailing 'T' often seen in distributor listings like Mouser (MAX6312UK46D3+T). Confirm RoHS compliance status (+) and ensure the specific threshold voltage matches design requirements before procurement.

Supervisors Selection Notes

Select this component when monitoring multiple rails such as 5V and 3.3V simultaneously. Ensure the 4.63V threshold aligns with the target supply voltage. Consider the SOT-23-5 package size for space-constrained designs. Verify that the open-drain output type suits the system logic levels.

Supervisors Part Context

Part of the MAX6305–MAX6313 series of 5-Pin, Multiple-Input, Programmable Reset ICs. These devices are specifically engineered to ignore fast transients on monitored supplies. The series offers various factory-programmed thresholds from 2.5V to 5.0V in 100mV increments.

Supervisors Replacement Considerations

Other variants within the MAX6305–MAX6313 family may serve as substitutes if different reset thresholds or timeout periods are required. Check datasheet for pin-compatible options with matching package and electrical characteristics.
