MAX6310UK45D1-T

Supervisors Overview

The MAX6310UK45D1-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed reset thresholds of 4.5V and adjustable settings. The device provides an active low, push-pull output and operates within a supply voltage range up to 5.5V. It utilizes a SOT-23-5 package with dimensions of 2.9mm length, 1.63mm width, and 1.1mm height. The IC offers a reset delay time of 1.4ms and consumes 8µA of operating supply current.

Supervisors Feature Summary

• Monitors multiple power supplies for system integrity
• Provides active low push-pull reset output
• Immune to short VCC transients

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific threshold voltage configuration against the datasheet, as suffixes indicate programmed values. Confirm package type is SOT-23-5. Check for lead-free compliance if required by assembly standards. Ensure the operating temperature range meets application requirements. Validate that the active low output logic matches the target system design.

Supervisors Selection Notes

Select this component when dual-supervision is required in a compact form factor. The 8µA current draw suits battery-powered designs. Verify that the 4.5V threshold aligns with the primary rail being monitored. Consider the 1.4ms reset delay for timing-sensitive resets. Ensure the SOT-23-5 footprint fits the PCB layout constraints.

Supervisors Part Context

Part of the MAX6305–MAX6313 series of 5-pin, multiple-input programmable reset ICs from Maxim Integrated. These devices are engineered to ignore fast transients on monitored supplies. The series includes various threshold options from 2.5V to 5.0V in 100mV increments. They are designed for portable applications due to low power consumption and small package size.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the MAX6305–MAX6313 family with matching threshold voltages. Verify that alternative parts maintain the same active low push-pull output type and SOT-23-5 package. Ensure equivalent reset delay times and supply current specifications.
