MAX6306UK31D1+T

Supervisors Overview

The MAX6306UK31D1+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features a fixed reset threshold voltage of 3V and monitors two inputs. The device provides an active low, open-drain output with a manual reset input. It operates within a supply voltage range up to 5.5V and supports an operating temperature range from 0°C to +70°C. The circuit draws 8µA of supply current and utilizes a SOT-23-5 package.

Supervisors Feature Summary

• Monitors multiple power supply rails for system integrity
• Includes manual reset input for user-initiated control
• Designed to ignore fast transients on monitored supplies

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Portable electronic devices requiring low supply current
• Embedded systems requiring multi-supervision

Supervisors Procurement Notes

Verify the specific suffix D1 corresponds to the 3V threshold and commercial temperature grade (0°C to +70°C) in the official datasheet. Confirm RoHS compliance status (+ suffix). Ensure the SOT-23-5 package matches your PCB footprint requirements before ordering.

Supervisors Selection Notes

Select this component when dual-supply supervision is required with a fixed 3V threshold. Consider the commercial temperature range limits. Compare against other MAX6306 variants if different thresholds or extended temperature ranges are needed. Verify the open-drain output compatibility with the target logic levels.

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. They provide reliable reset generation by ignoring fast transients on any monitored supply.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX6306 series with adjusted threshold voltages or temperature grades. Verify functional equivalence regarding manual reset capability and output type.
