MAX6310EUK46D3+T

Supervisors Overview

The MAX6310EUK46D3+T is a CMOS supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed thresholds of 3.3 V and 5 V. The device provides an active low, push-pull reset output with a fixed delay time of 1.4 ms. It operates within a supply voltage range up to 5.5 V and consumes only 8 µA of operating supply current. Packaged in a SOT-23-5 surface-mount case, it lacks manual reset, watchdog timers, or battery backup switching capabilities.

Supervisors Feature Summary

• Monitors two independent power supply inputs simultaneously
• Provides active low push-pull reset signal generation
• Operates with ultra-low quiescent current consumption

Supervisors Applications

• Personal computer system power monitoring
• Portable electronic device supervision
• Multi-rail embedded system reset management

Supervisors Procurement Notes

Verify the specific suffix D3 against official Analog Devices documentation to confirm factory-programmed threshold configurations. Ensure the SOT-23-5 package variant matches the design requirements. Cross-reference the exact part number with manufacturer databases to validate current production status and availability constraints before finalizing procurement plans.

Supervisors Selection Notes

Select this component when simultaneous monitoring of dual voltage rails is required without manual intervention. The fixed 1.4 ms reset delay suits applications tolerant of standard startup times. Consider the absence of watchdog functionality if processor protection is needed. Verify that the 5.5 V maximum rating aligns with the highest monitored supply level.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs. These devices are optimized for portable applications due to their small package size and low power consumption. The series is engineered to ignore fast transients on monitored supplies, ensuring stable reset assertion during normal operation.

Supervisors Replacement Considerations

The MAX6309EUK46D3+T serves as a functional substitute within the same family, offering identical dual-input monitoring and threshold specifications. Differences may exist in output driver types; verify compatibility between push-pull and open-drain configurations during replacement.
