ADM6318CY46ARJZ-R7

Supervisors Overview

The ADM6318CY46ARJZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for power supply management. It operates within a maximum supply voltage of 5.5 V and features a reset threshold of 4.63 V with an overvoltage threshold of 4.699 V. The device provides a push-pull active low output and includes a watchdog timer function, but lacks manual reset and battery backup capabilities. It consumes 20 uA of operating current and maintains an accuracy of 2.5%. The component is housed in a SOT-23-5 package and supports industrial temperature ranges from -40 C to +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring without requiring manual reset inputs
• Provides a push-pull active low reset output stage for direct logic interfacing
• Ensures power supply glitch immunity and valid reset outputs down to low supply voltages

Supervisors Applications

• Embedded systems requiring automated watchdog supervision
• Industrial control units needing reliable power management
• Consumer electronics utilizing single-input voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix ARJZ-R7 against official Analog Devices documentation to confirm the reel packaging configuration and exact electrical tolerances. Ensure the selected variant matches the required 4.63 V threshold and push-pull output characteristics for your design. Cross-reference the RoHS compliance status and lead-free specifications with the manufacturer's latest product change notices before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a push-pull output is preferred over open-drain configurations for driving loads directly. The integrated watchdog feature eliminates the need for external timing components, simplifying board layout. Verify that the 4.63 V threshold aligns with the target supply rail and that the 20 uA quiescent current fits the system's power budget constraints.

Supervisors Part Context

This part belongs to the ADM6318 series of supervisory circuits from Analog Devices. It is distinct from similar models like the ADM6320, which utilizes an open-drain output instead of push-pull. The CY46 designation indicates the specific 4.63 V threshold voltage setting within the family's available options.

Supervisors Replacement Considerations

Direct substitutes include other ADM6318 variants with different threshold voltages if the 4.63 V setting is not critical. Models such as ADM6318CY29ARJZ-R7 offer identical functionality with a 2.9 V threshold.
