MAX6310UK30D3-T

Supervisors Overview

The MAX6310UK30D3-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with active low, push-pull outputs and a reset delay time of 1570 ms. The device operates within a supply voltage range up to 5.5 V and draws an operating supply current of 8 uA. It includes overvoltage and undervoltage thresholds of 2.538 V and 2.463 V respectively. The component is housed in a SOT-23-5 package measuring 2.9 mm in length, 1.63 mm in width, and 1.1 mm in height.

Supervisors Feature Summary

• Monitors two independent power supply inputs for system integrity
• Provides active low push-pull reset output signals
• Operates with ultra-low supply current consumption

Supervisors Applications

• Monitoring dual power rails in portable electronic devices
• Supervising voltage levels in personal computer systems
• Ensuring valid reset states during power-up sequences

Supervisors Procurement Notes

Verify the specific suffix D3 corresponds to the required reset timeout period and threshold configuration before procurement. Confirm that the SOT-23-5 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final application. Cross-reference the manufacturer datasheet revision to confirm pinout compatibility.

Supervisors Selection Notes

Select this component when simultaneous monitoring of two distinct voltage sources is required. The fixed reset delay and specific threshold values suit applications where transient immunity is critical. Consider the low supply current for battery-operated designs. Verify that the active low output polarity matches the downstream logic requirements.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs manufactured by Maxim Integrated. These circuits are engineered to ignore fast transients on monitored supplies while guaranteeing reset validity down to 1V. The family offers various factory-programmed thresholds and timeout periods to suit diverse system architectures.

Supervisors Replacement Considerations

Compatible substitutes include other members of the MAX6305–MAX6313 series with matching SOT-23-5 packaging. Verify equivalent threshold voltages and reset delay times when selecting alternative part numbers from the same product line.
