MAX6306UK47D2

Supervisors Overview

The MAX6306UK47D2 is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It asserts a system reset if any monitored supply falls outside the programmed threshold, specifically targeting a 4.7V threshold in this variant. The device features an active-low open-drain output and includes a manual reset input. It operates within a supply voltage range up to 5.5V with a typical quiescent current of 15µA. Packaged in a compact SOT-23-5 format, it ignores fast transients on monitored supplies.

Supervisors Feature Summary

• Monitors multiple power supply inputs simultaneously for system integrity
• Asserts reset signal when monitored voltages deviate from factory-programmed thresholds
• Includes manual reset input capability for external control
• Designed to ignore fast transients on monitored supply lines

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable applications requiring low supply current
• Microprocessor supervisory circuits in embedded systems

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free specifications against current datasheet revisions. Check for obsolescence notices as the part may be scheduled for discontinuation. Ensure packaging details match project requirements for surface-mount assembly.

Supervisors Selection Notes

Select this component when fixed threshold supervision at 4.7V is required for multi-rail systems. Consider the SOT-23-5 package size constraints and 15µA standby current suitability for portable designs. Verify that the active-low open-drain output configuration aligns with the target logic interface. Evaluate thermal dissipation limits relative to the application environment.

Supervisors Part Context
