MAX6805US44D3+

Supervisors Overview

The MAX6805US44D3+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 4.375 V with an overvoltage threshold of 4.484 V. The device provides a manual reset function and includes a reset delay time of 225 ms. It consumes only 7 uA of operating power current and supports a maximum power dissipation of 571 mW. Designed for surface mount installation, it is housed in a TO-253-4 package and functions reliably across a temperature range from -40 C to +85 C.

Supervisors Feature Summary

• Provides reliable microprocessor supervision through dedicated reset output signaling
• Integrates manual reset capability for system control flexibility
• Maintains ultra-low quiescent current consumption for power-sensitive applications

Supervisors Applications

• Microprocessor reset circuits
• Power-on reset supervision
• Battery-powered system monitoring

Supervisors Procurement Notes

Verify the specific suffix D3+ against official Analog Devices documentation to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status via the manufacturer datasheet. Ensure the TO-253-4 package dimensions align with your PCB footprint specifications before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a single-input voltage supervisor with manual reset functionality is required. The 4.375 V threshold suits standard 5 V logic systems. Consider the 7 uA current draw for battery efficiency. Verify that the TO-253-4 package is suitable for your assembly process compared to smaller SOT packages if space is constrained.

Supervisors Part Context

This part belongs to the MAX6805 series of low-power supervisors. It is designed to simplify microprocessor revival and reset management. The device integrates essential supervision features into a compact form factor, targeting embedded systems requiring robust power monitoring without complex external components.

Supervisors Replacement Considerations

Check Analog Devices documentation for direct cross-references. The MAX6805UK44D3+ may offer similar electrical performance in a different package. Verify pin compatibility and threshold voltages before substitution.
