ADM6315-44D3ARTRL7

Supervisors Overview

The ADM6315-44D3ARTRL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as an open-drain microprocessor supervisor. It operates within a supply voltage range of 2.5 V to 5 V and features a single monitored input. The device provides an active-low, open-drain reset output with a manual reset capability. Key electrical parameters include a threshold voltage of 4.40 V, a reset delay time of 28 ms, and a maximum power supply voltage of 5.5 V. It is housed in a surface-mount SOT-143-4 package.

Supervisors Feature Summary

• Provides reliable system reset via open-drain output when supply voltage drops below the specified threshold
• Includes manual reset functionality for controlled system initialization
• Operates within standard low-voltage ranges suitable for digital logic monitoring

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Digital logic circuit protection

Supervisors Procurement Notes

Verify the specific suffix ARTRL7 against official Analog Devices documentation to confirm reel packaging and tape specifications. Ensure the part number matches the exact threshold voltage variant required for your design. Cross-reference with authorized distributors to confirm current availability status, as supply conditions may vary.

Supervisors Selection Notes

Select this component when a fixed 4.40 V threshold is required for single-input voltage monitoring. Confirm that the open-drain output configuration aligns with the pull-up requirements of the connected microprocessor or logic interface. Verify that the 28 ms reset delay meets the timing constraints of the target application.

Supervisors Part Context

This component belongs to the ADM6315 family of microprocessor supervisory circuits from Analog Devices. These devices are engineered for compact surface-mount applications, offering precise voltage monitoring in small form factors like the SOT-143-4 package. The series supports various threshold voltages to accommodate different logic families.

Supervisors Replacement Considerations

Check for ADM6315 variants with identical 4.40 V thresholds and SOT-143-4 packaging. Verify functional compatibility regarding reset delay times and output drive capabilities before substitution.
