ADM8316WAY27ARJZR7

Supervisors Overview

The ADM8316WAY27ARJZR7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring voltage levels in electronic systems. It operates within an extended temperature range of -40°C to +125°C and is housed in a compact SOT-23-5 surface-mount package. The device features a fixed threshold voltage of 2.7V, ensuring precise detection of power supply anomalies. Key functional attributes include an integrated manual reset input, a watchdog timer with a timeout period of 1.4 seconds, and a push-pull output configuration. This component is qualified under the AEC-Q100 standard, indicating its suitability for automotive applications requiring high reliability and robust performance under varying environmental conditions.

Supervisors Feature Summary

• Integrated manual reset functionality allows for direct user intervention to trigger a system reset via a dedicated pin.
• Built-in watchdog timer provides automated recovery from software faults or processor hangs without external components.
• Push-pull output stage delivers strong drive capability for reliable signal transmission to downstream logic circuits.

Supervisors Applications

• Automotive electronic control units requiring AEC-Q100 qualified supervision
• Industrial systems needing watchdog protection against software lockups
• Portable devices utilizing low-voltage power supplies

Supervisors Procurement Notes

Verify the complete part number including suffixes such as 'RJZR7' to ensure correct packaging and tape-and-reel specifications. Confirm that the specific variant matches the required threshold voltage and output type for your design. Check current availability status as distribution may vary by region. Ensure compliance with RoHS directives if applicable to your manufacturing process. Cross-reference with official Analog Devices documentation for any recent updates or revisions to the datasheet.

Supervisors Selection Notes

Select this component when a combination of voltage supervision, manual reset capability, and watchdog timer is required in a small footprint. The 2.7V threshold suits applications powered by lithium-ion batteries or regulated 3.3V rails. The push-pull output eliminates the need for external pull-up resistors, simplifying board layout. Consider the operating temperature range to ensure compatibility with the intended environment. Verify that the SOT-23-5 package fits within the mechanical constraints of the enclosure.

Supervisors Part Context

This part belongs to the ADM8316 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and output configurations to suit different system requirements. The 'W' indicates wide temperature operation, while 'A' specifies the 2.7V threshold. The 'Y' denotes the watchdog timer feature, and '27' confirms the threshold value. The suffix 'RJZR7' typically refers to the reel packaging format used for automated assembly processes.

Supervisors Replacement Considerations

Direct replacements must match the 2.7V threshold, push-pull output, and watchdog functionality. Parts like ADM8316WAY30ARJZR7 offer similar features but with a different threshold voltage. Ensure any substitute maintains the same package size and pinout to avoid PCB redesign. Verify that alternative parts meet the same AEC-Q100 qualification if used in automotive contexts.
