MAX6306UK46D3

Supervisors Overview

The MAX6306UK46D3 is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features a SOT-23-5 package and supports a maximum supply voltage of 5.5V. The device monitors two inputs with a reset threshold voltage of 4.6V. It provides an active low, open-drain output and includes a manual reset input. The reset delay time is 1.4ms, and the operating supply current is 8µA.

Supervisors Feature Summary

• Monitors multiple power supply rails simultaneously
• Includes manual reset input capability
• Features active low open-drain output configuration

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V supplies
• Portable applications requiring low supply current
• Systems requiring transient immunity on monitored supplies

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices. Ensure packaging specifications match design requirements. Validate datasheet revisions against production batches.

Supervisors Selection Notes

Select this part when multi-input supervision is required in compact designs. Consider the fixed 4.6V threshold and 8µA quiescent current. Verify compatibility with system voltage levels and reset timing requirements. Evaluate thermal performance within the specified operating temperature range.

Supervisors Part Context

Part of the MAX6305–MAX6313 family of 5-pin programmable reset ICs. Designed for portable applications due to low current consumption and small package size. Factory-programmed thresholds eliminate external resistor networks.

Supervisors Replacement Considerations

Check MAX6306 variants with different suffixes for threshold adjustments. Verify pinout compatibility with existing layouts before substitution.
