ADM8316WBX46ARJZR7

Supervisors Overview

The ADM8316WBX46ARJZR7 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 qualified under the AEC-Q100 standard for automotive applications. The device features a single monitored input with a threshold voltage of 4.63V and provides a push-pull/totem pole output configuration. It includes a manual reset function and incorporates a watchdog timer with a timeout period of 102ms. The reset delay time is specified at 30ms, ensuring reliable system recovery. Packaged in a compact SOT-23-5 surface-mount format, it supports reel, cut tape, and MouseReel packaging options.

Supervisors Feature Summary

• Integrated manual reset capability allowing external control over system restart sequences
• Built-in watchdog timer with defined timeout duration to detect software malfunctions
• Automotive-grade qualification ensuring reliability in harsh operating environments
• Push-pull output stage providing robust drive capability for downstream logic

Supervisors Applications

• Automotive electronic control units requiring high-reliability power supervision
• Industrial systems utilizing microcontrollers that need watchdog protection
• Portable devices operating within wide temperature extremes
• Embedded systems demanding manual reset functionality for service access

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity upon receipt, as SOT-23-5 components are sensitive to moisture and physical damage. Ensure compatibility with existing board layouts regarding pinout alignment. Check for specific ordering suffixes if variant selection is required. Maintain proper ESD handling procedures during storage and assembly to prevent latent defects.

Supervisors Selection Notes

Choose this component when automotive qualification and manual reset features are mandatory. The 4.63V threshold suits 5V nominal supply systems. Consider the 102ms watchdog timeout against processor execution speeds. Evaluate the SOT-23-5 footprint against available PCB space. Compare performance requirements against other ADM8316 variants if different thresholds or output types are needed.

Supervisors Part Context

This part belongs to the ADM8316 series of supervisory circuits from Analog Devices. The series offers various voltage thresholds and feature combinations tailored for power management needs. The WBX46 suffix indicates the specific 4.63V threshold and push-pull output configuration. The RJZR7 suffix denotes the reel packaging format. This family is widely used in applications requiring precise voltage monitoring and system reset control.

Supervisors Replacement Considerations

Direct substitutes include other ADM8316 variants with matching 4.63V thresholds and push-pull outputs, such as ADM8316WDW49ARJZR7 if threshold differences are acceptable. Verify pinout compatibility before substitution. Alternative manufacturers may offer similar functions but require thorough electrical parameter comparison.
