MAX6310UK40D2+

Supervisors Overview

The MAX6310UK40D2+ is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed reset thresholds of 3.3 V and 5 V. The device provides an active low, push-pull output and includes a manual reset input. It operates within a supply voltage range up to 5.5 V, consumes 8 µA of operating supply current, and offers a reset delay time of 1.57 s. Packaged in a SOT-23-5 format, it supports operation from 0°C to +70°C.

Supervisors Feature Summary

• Monitors dual power supply inputs for system integrity
• Provides active low push-pull reset signal output
• Includes manual reset capability for user control

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix D2 against the official datasheet to confirm the exact reset timeout period and threshold configuration. Ensure the component matches the required package type and temperature range for your application environment before finalizing procurement.

Supervisors Selection Notes

Select this part when dual-supervision of distinct voltage rails is required alongside manual reset functionality. Compare the 1.57 s reset delay against system startup requirements. Consider the 8 µA quiescent current for battery-sensitive designs.

Supervisors Part Context

This component belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input programmable reset ICs. These devices are engineered to ignore fast transients on monitored supplies and guarantee valid resets down to 1 V. The series is optimized for portable electronics due to its small footprint and low power consumption.
