ADM6316DZ26ARJ-RL7

Supervisors Overview

The ADM6316DZ26ARJ-RL7 is a single-channel power supply management circuit manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 5-pin SOT-23 package. The device features a fixed reset threshold voltage of 2.669 V, with a maximum supply voltage of 5.5 V and a minimum operating voltage of 1 V. It includes a watchdog timer with a reset delay time of 2.24 s and supports manual reset input. The component draws a typical operating current of 20 µA and provides push-pull output stages.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring alongside voltage supervision capabilities
• Provides manual reset input functionality for external control over the reset state
• Delivers glitch immunity to ensure stable operation during power supply fluctuations
• Maintains valid reset output signals even at low supply voltages down to 1 V

Supervisors Applications

• Microprocessor systems requiring reliable startup sequencing
• Portable equipment needing low-power supervision
• Controllers demanding watchdog timer protection
• Intelligent instruments utilizing industrial-grade components

Supervisors Procurement Notes

Verify the specific reset threshold voltage of 2.669 V against design requirements, as this value is fixed for the DZ suffix. Confirm RoHS compliance status, noting that some variants in this series are lead-free while others may not be. Ensure the SOT-23-5 package dimensions match the PCB footprint constraints. Check for any specific ordering suffixes that might affect packaging or environmental compliance before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed 2.669 V threshold is required for the monitored rail. Consider the 2.24 s reset delay if longer initialization times are necessary for the target system. Evaluate the 20 µA quiescent current against battery life requirements for portable applications. Verify that the push-pull output stage meets the drive requirements of the downstream logic without additional buffering.

Supervisors Part Context

This part belongs to the ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ADM6321/ADM6322 family of supervisory circuits. These devices share common features such as watchdog timers, manual reset inputs, and low-power consumption. The family offers various threshold options ranging from 2.5 V to 5 V in 100 mV increments, packaged in a compact 5-lead SOT-23 form factor suitable for space-constrained designs.

Supervisors Replacement Considerations

Other parts in the ADM6316 series with different suffixes (e.g., DZ25, DZ27) offer different fixed threshold voltages but share the same package and functional interface. Ensure the replacement maintains the 2.669 V threshold or adjust circuit design accordingly. Verify that the substitute part supports the same industrial temperature range and watchdog timeout characteristics.
