MAX6312UK46D3+T

Supervisors Overview

The MAX6312UK46D3+T is a CMOS microprocessor supervisory circuit designed to monitor power supply voltages. It operates within a supply voltage range of up to 5.5V and features a fixed reset threshold voltage of 4.6V. The device provides an active-low, open-drain reset output with a manual reset input capability. It is housed in a compact SOT-23-5 surface-mount package. Key electrical characteristics include a maximum operating current of 8µA and a guaranteed reset valid down to VCC = 1V. The component is lead-free and RoHS compliant.

Supervisors Feature Summary

• Monitors single power supply voltage with factory-programmed threshold
• Provides active-low open-drain reset signal with manual reset input
• Ensures reset validity down to low supply voltage levels
• Immune to short transients on the monitored supply line

Supervisors Applications

• Personal computer system power monitoring
• Portable electronic device power management
• Microprocessor system supervision
• Battery-powered equipment voltage tracking

Supervisors Procurement Notes

Verify the specific suffix D3 against the manufacturer's official datasheet to confirm the exact reset timeout period and threshold tolerance. Confirm availability status as distribution channels may list limited stock or obsolete status for this specific variant. Ensure the ordering part number matches the required package type and temperature rating for your design.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with a fixed 4.6V threshold is required. Consider the 8µA supply current for battery-sensitive designs. Verify that the open-drain output configuration aligns with the downstream logic requirements. Check if the manual reset feature is necessary for the specific application workflow.

Supervisors Part Context

This part belongs to 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, catering to diverse standard voltage rails in portable and PC applications.

Supervisors Replacement Considerations

Other variants within the MAX6312 family offer different threshold voltages. Cross-reference the MAX6312UKxxD3+T series for alternative fixed thresholds. Ensure any substitute maintains the SOT-23-5 package and compatible electrical specifications.
