MAX6309UK46D4

Supervisors Overview

The MAX6309UK46D4 is a multi-voltage supervisor manufactured by Analog Devices Inc./Maxim Integrated. It monitors two input voltages with a threshold of 4.63V and features an active low push-pull output. The device includes a manual reset input and operates within a temperature range of -40°C to +125°C. It consumes 7µA of supply current and supports a maximum voltage of 5.5V. The component is housed in a uDFN-6 package.

Supervisors Feature Summary

• Monitors multiple power supplies for system integrity
• Provides active low push-pull reset signal
• Includes manual reset capability for user control

Supervisors Applications

• Portable electronic systems requiring dual voltage monitoring
• Personal computer power supply supervision
• Battery-powered devices needing low standby current

Supervisors Procurement Notes

Verify the exact suffix configuration against the manufacturer's official datasheet, as variations exist within the MAX6309 family. Confirm availability status directly with authorized distributors, as this specific part number may be subject to limited supply or obsolescence. Ensure the selected variant matches the required operating temperature range and package type for your design.

Supervisors Selection Notes

Select this component when dual-supply monitoring is required with a fixed 4.63V threshold. Consider the uDFN-6 package for space-constrained designs. Verify that the active low push-pull output drives the target logic level correctly. Check if the manual reset feature is necessary for the specific application sequence.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of CMOS microprocessor supervisory circuits designed by Maxim Integrated. These devices are engineered to monitor more than one power supply simultaneously. They assert a system reset if any monitored supply falls outside the programmed threshold, making them suitable for complex power management scenarios.

Supervisors Replacement Considerations

Check for MAX6309 variants with different thresholds or packages. Verify compatibility with MAX6387 series if single/dual low-voltage monitoring is acceptable. Ensure substitute parts match the uDFN-6 footprint and electrical characteristics.
