MAX6306UK44D3+

Supervisors Overview

The MAX6306UK44D3+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed reset thresholds of 3.3V and 5V. The device provides an active-low, open-drain reset output with a manual reset input capability. Operating within a supply voltage range up to 5.5V, it draws only 8µA of supply current. The IC is housed in a compact SOT-23-5 package and includes a fixed reset delay time of 1.4ms.

Supervisors Feature Summary

• Monitors two independent power supply rails simultaneously for system integrity
• Provides active-low open-drain reset signal assertion when voltages fall below programmed thresholds
• Includes manual reset input pin for external control override
• Operates with ultra-low supply current suitable for portable applications

Supervisors Applications

• Monitoring 5V and 3.3V supplies in personal computer systems
• Portable electronic devices requiring low-power supervision
• Multi-rail power supply monitoring in embedded systems

Supervisors Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging if reel procurement is required. Confirm RoHS compliance status through official Analog Devices documentation. Check current availability as distribution may vary. Ensure the specific threshold configuration matches design requirements before ordering.

Supervisors Selection Notes

Select this component when dual-supervision of distinct voltage levels is necessary. The fixed 3.3V and 5V thresholds suit standard logic and power rail monitoring. Consider the open-drain output requirement for pull-up resistor implementation. Verify thermal dissipation limits against application conditions.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs. These devices are engineered to ignore fast transients on monitored supplies. The series offers various threshold combinations in 100mV increments, packaged in SOT-23-5 form factors for space-constrained designs.

Supervisors Replacement Considerations

Other MAX6306 variants with different threshold suffixes (e.g., D3, D4) offer alternative voltage settings. Cross-reference with MAX6307 or MAX6310 series members for similar functionality but potentially different output types such as push-pull configurations.
