ADM6316BX46ARJZ-R7

Supervisors Overview

The ADM6316BX46ARJZ-R7 is a supervisory circuit from Analog Devices Inc. designed to monitor power supply voltage levels and code execution integrity in microprocessor-based systems. It features a fixed reset threshold voltage of 4.6V, selected from 26 options ranging from 2.5V to 5V in 100mV increments. The device includes an on-chip watchdog timer with four timeout options (6.3ms, 102ms, 1600ms, and 25.6s typical) and a manual reset input. It offers low power consumption of 5μA and guarantees a valid reset output down to VCC = 1V. The component is housed in a 5-lead SOT-23 package and operates within the industrial temperature range.

Supervisors Feature Summary

• Integrates a watchdog timer for monitoring code execution integrity and asserting resets if strobing fails within preset periods.
• Provides a manual reset input allowing external assertion of a reset signal via push button.
• Features multiple reset output stage configurations including push-pull active low, open-drain active low, and push-pull active high.
• Ensures power supply glitch immunity and maintains valid reset output validity down to 1V supply voltage.

Supervisors Applications

• Microprocessor systems
• Controllers
• Intelligent instruments

Supervisors Procurement Notes

Verify the specific suffix codes against the official Analog Devices datasheet to confirm the exact reset threshold, timeout selection, and output configuration. Ensure the ordering part number matches the required electrical parameters for the target application. Confirm RoHS compliance status and packaging details directly with the manufacturer or authorized distributors prior to procurement.

Supervisors Selection Notes

Select this component when a fixed 4.6V reset threshold is required alongside integrated watchdog and manual reset functionalities. Consider the available reset timeout and watchdog timeout options to match system timing requirements. Evaluate the necessary reset output stage type (push-pull vs. open-drain) to ensure compatibility with the downstream logic interface.

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 low power consumption, industrial temperature specification, and the 5-lead SOT-23 package. Variations within the family are defined by different combinations of watchdog inputs, manual reset inputs, and output stage configurations.

Supervisors Replacement Considerations

Substitute parts must be verified against the official Analog Devices cross-reference list. Only public confirmed substitute part numbers should be considered. Generic equivalents may lack specific features like the manual reset input or exact timeout options.
