ADM6316DZ31ARJ-RL7

Supervisors Overview

The ADM6316DZ31ARJ-RL7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single voltage rails. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed reset threshold of 3.08 V with an accuracy of ±2.5%. The device includes a watchdog timer, manual reset input, and push-pull active-low reset output. It consumes low power, with typical quiescent current of 3 µA, and guarantees reset validity down to 1 V. The component is specified over the industrial temperature range of -40°C to +85°C and is housed in a compact 5-lead SOT-23 package.

Supervisors Feature Summary

• Integrates watchdog timer functionality with manual reset capability for enhanced system reliability
• Provides glitch immunity against power supply transients to prevent false resets
• Offers multiple reset output configurations including push-pull active-low, open-drain active-low, and push-pull active-high options

Supervisors Applications

• Microprocessor systems requiring reliable power supervision
• Controllers needing watchdog protection against software hangs
• Portable equipment demanding low power consumption
• Intelligent instruments operating in industrial environments

Supervisors Procurement Notes

Verify the specific suffix 'DZ' indicates the leaded (non-RoHS) variant when sourcing, as 'Z' typically denotes RoHS compliance in this series. Confirm the reset timeout configuration matches the design requirements, as the datasheet specifies four distinct timeout options. Ensure the manual reset input logic level compatibility aligns with the host microcontroller interface. Cross-reference the exact part number with official Analog Devices documentation to confirm availability status and manufacturing origin details prior to procurement.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for standard logic or analog supply monitoring. The integrated watchdog feature eliminates the need for external timing components, simplifying board layout. Consider the push-pull output stage if driving higher capacitive loads compared to open-drain alternatives. Verify that the 3 µA quiescent current meets the standby power budget constraints of the application. Ensure the SOT-23-5 footprint fits within the available PCB area constraints.

Supervisors Part Context

This part belongs to the ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ADM6321/ADM6322 family of supervisory circuits. These devices share common architectural features such as watchdog timers and manual reset inputs but differ primarily in their reset threshold voltages and timeout durations. The ADM6316 specifically offers 26 threshold options ranging from 2.5 V to 5 V in 100 mV increments, allowing precise customization for various supply rail monitoring needs.
