MAX6306UK30D2+

Supervisors Overview

The MAX6306UK30D2+ is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features a fixed reset threshold voltage of 3.0V and includes a manual reset input. The device operates within a supply voltage range up to 5.5V and provides an active-low, open-drain reset output. It is housed in a compact SOT-23-5 package with dimensions of 2.9 mm length. The component supports an operating temperature range from -40°C to +85°C and consumes low supply current suitable for portable applications.

Supervisors Feature Summary

• Monitors multiple power supply inputs simultaneously
• Asserts system reset when monitored voltages fall outside programmed thresholds
• Includes manual reset input capability
• 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
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the specific suffix D2 corresponds to the 3.0V threshold variant in official Maxim Integrated documentation. Confirm RoHS compliance status (+ suffix) and package type (SOT-23-5). Ensure the manufacturer source is Analog Devices or Maxim Integrated. Cross-reference the full part number against current datasheets to confirm availability and exact electrical specifications.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required. The fixed 3.0V threshold suits applications where one rail must be tracked against a specific limit. The SOT-23-5 package minimizes board space. Consider the manual reset feature if external reset control is needed. Verify that the transient immunity meets the application's noise environment requirements.

Supervisors Part Context

Part of the MAX6305–MAX6313 family of 5-pin, multiple-input, programmable reset ICs. These devices are optimized for monitoring dual power supplies like 5V and 3.3V. The family offers various factory-programmed thresholds from 2.5V to 5.0V in 100mV increments. They share common features including low current consumption and small package size.

Supervisors Replacement Considerations

Other variants within the MAX6305–MAX6313 series may serve as substitutes if different reset thresholds are acceptable. Verify pinout compatibility and package similarity. Check if alternative parts support the same manual reset functionality and multi-supervision capabilities.
