ADM6316DZ31ARJZ-R7

Supervisors Overview

The ADM6316DZ31ARJZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-channel power supply voltages. It integrates a watchdog timer and a manual reset input within a compact 5-lead SOT-23 package. The device features a fixed reset threshold voltage of 3.08 V with an accuracy of ±2.5%. It provides a push-pull active-low reset output and supports a reset delay time of 1.6 s. The component operates within a supply voltage range up to 5.5 V and maintains functionality down to 1 V. It is specified for industrial temperature ranges from -40°C to +85°C, ensuring reliable performance in embedded systems.

Supervisors Feature Summary

• Integrates a watchdog timer with configurable timeout options and a manual reset input for system control flexibility.
• Provides a push-pull active-low reset output stage that remains valid down to a supply voltage of 1 V.
• Features low power consumption characteristics suitable for battery-operated portable equipment applications.

Supervisors Applications

• Microprocessor systems requiring voltage supervision
• Portable equipment with limited power budgets
• Controllers needing watchdog timer functionality

Supervisors Procurement Notes

Verify the specific suffix ARJZ-R7 against the manufacturer's current datasheet to confirm packaging format and tape-and-reel specifications. Ensure the 3.08 V threshold matches the target application requirements. Confirm RoHS compliance status as indicated in official documentation before procurement.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required alongside integrated watchdog and manual reset capabilities. Consider the SOT-23-5 package for space-constrained designs. Verify that the 1.6 s reset delay and push-pull output drive meet the system timing and load requirements compared to open-drain alternatives.

Supervisors Part Context

This part belongs to the ADM6316 series of supervisory circuits from Analog Devices. The series offers various reset thresholds and timeout options within the same 5-lead SOT-23 footprint. The DZ31 designation specifically indicates the 3.08 V threshold variant, while the RJZ-R7 suffix denotes the reel packaging configuration.

Supervisors Replacement Considerations

Check for ADM6316 variants with different threshold voltages if the 3.08 V setting is not optimal. Other parts in the ADM6316 family share pinouts but may differ in reset delay or output type. Verify compatibility with existing PCB layout and firmware watchdog handling routines.
