MAX6310UK45D3-T

Supervisors Overview

The MAX6310UK45D3-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed thresholds of 3.3V and 5V. The device provides an active low, push-pull output and includes a manual reset input. It operates within a supply voltage range up to 5.5V and offers a reset delay time of 1.4ms. The component is housed in a compact SOT-23-5 package and consumes 8µA of operating supply current.

Supervisors Feature Summary

• Monitors two independent power supply rails simultaneously
• Provides active low push-pull reset signal output
• Includes manual reset input for system control
• Immune to fast transients on monitored supplies

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable applications requiring low supply current
• Microprocessor supervisory circuits
• Battery-powered equipment requiring voltage supervision

Supervisors Procurement Notes

Verify the exact suffix D3-T against official Analog Devices documentation to confirm pinout and threshold specifications. Confirm RoHS compliance status as some variants may differ. Check current lifecycle status as Maxim Integrated products may be subject to obsolescence or limited availability through distributors.

Supervisors Selection Notes

Select this component when dual-supervision of 3.3V and 5V rails is required in a small footprint. The push-pull output allows direct driving of logic inputs without external pull-ups. Ensure the 1.4ms reset delay meets system timing requirements. Verify that the SOT-23-5 package fits the PCB layout constraints.

Supervisors Part Context

Part of the MAX6305–MAX6313 family of 5-pin multiple-input programmable reset ICs. These devices are optimized for portable applications due to low power consumption and small package size. The family offers various threshold combinations and timeout periods to suit different power sequencing needs.

Supervisors Replacement Considerations

Check MAX6310UK45D3+T for lead-free variant compatibility. Consider MAX6309 series for similar functionality with open-drain outputs if push-pull is not required. Verify pin-to-pin compatibility with other MAX63xx variants before substitution.
