AZ7031RTR-G1

Supervisors Overview

The AZ7031RTR-G1 is a supervisory circuit voltage detector manufactured by Diodes Incorporated. It operates within a supply voltage range of 800 mV to 18 V and features a fixed threshold voltage of 3.1 V. The device utilizes an open collector output type and includes a built-in watchdog timer for system reliability. It supports chip enable functionality and battery backup switching without manual reset capabilities. Designed for surface mount applications, it is housed in an SOT-89-3 package with a power dissipation rating of 500 mW.

Supervisors Feature Summary

• Integrates a watchdog timer to monitor system operation and prevent software lockups.
• Provides battery backup switching capability to maintain data integrity during power transitions.
• Features chip enable control for flexible power management and low standby current consumption.

Supervisors Applications

• Microprocessor reset generation in embedded systems
• Watchdog timer implementation for industrial controllers
• Battery backup switching in portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix G1 against the manufacturer's latest datasheet to confirm RoHS compliance and material declarations. Ensure the SOT-89-3 package dimensions match your PCB footprint requirements. Confirm that the open collector output configuration aligns with your downstream logic interface needs before finalizing procurement.

Supervisors Selection Notes

Select this component when a 3.1 V threshold is required for single-supply monitoring. The integrated watchdog timer distinguishes it from basic voltage detectors. Verify that the 18 V maximum input voltage suits your application rails. Consider the SOT-89-3 package constraints regarding thermal dissipation and board space availability compared to through-hole alternatives.

Supervisors Part Context

This part belongs to the AZ70xx series of supervisory circuits from Diodes Incorporated. It shares functional similarities with other variants like the AZ7025 and AZ7045 but differs in threshold voltage and package options. The RTR suffix indicates reel packaging for automated surface mount assembly processes.
