ADM6320CW33ARJZ-R7

Supervisors Overview

The ADM6320CW33ARJZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed for power supply management in microprocessor systems. It operates within an industrial temperature range of -40°C to +85°C and is housed in a 5-lead SOT-23 package. The device features a fixed reset threshold voltage of 3.3V, ensuring reliable monitoring of the input supply. It includes a manual reset input and offers low power consumption characteristics with a typical operating current of 5 μA. The reset output is guaranteed valid down to VCC = 1V, providing robust glitch immunity.

Supervisors Feature Summary

• Integrates watchdog timer functionality with manual reset capability for enhanced system reliability
• Provides push-pull or open-drain reset output stages compatible with various logic families
• Ensures power supply glitch immunity and valid reset signals at low voltages

Supervisors Applications

• Microprocessor systems requiring supervised power rails
• Portable equipment needing low standby current
• Industrial control units operating in extended temperature ranges

Supervisors Procurement Notes

Verify the specific suffix 'CW33' confirms the 3.3V threshold variant when sourcing. Confirm RoHS compliance status as indicated by the 'Z' suffix in the part number. Check for lead-free certification if required by your manufacturing standards. Ensure the SOT-23-5 package matches your PCB footprint requirements. Validate that the manual reset pin configuration aligns with your system design.

Supervisors Selection Notes

Select this component when a fixed 3.3V supervision threshold is required for single-supply applications. Consider the 5-lead SOT-23 package for space-constrained designs. Evaluate the need for manual reset functionality versus automatic-only supervision. Compare the 5 μA quiescent current against other supervisors if battery life is critical. Ensure the industrial temperature range meets your environmental specifications.

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 multiple timeout options and low power consumption. The ADM6320 series specifically integrates watchdog timers and manual reset inputs. Variants differ primarily by reset threshold voltage and output stage configuration.

Supervisors Replacement Considerations

Direct substitutes include other ADM6320 variants with different threshold voltages, such as ADM6320CW29ARJZ-R7 (2.93V) or ADM6320CW47ARJZ-R7 (4.7V), provided the voltage level matches the application requirement. Cross-referencing with ADM6316 or ADM6321 series parts may be necessary if watchdog functionality is not needed.
