ADM8322WC26ARJZR7

Supervisors Overview

The ADM8322WC26ARJZR7 is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring voltage levels in electronic systems. It features a fixed reset threshold of 2.625 V and operates within a supply voltage range of 1.0 V to 5.5 V. The device provides a push-pull active-low reset output with a typical timeout of 140 ms. It includes an integrated watchdog timer with a 1.6-second timeout period and supports manual reset functionality via an MR pin. The component is housed in a compact 5-lead SOT-23 package, suitable for surface-mount applications across industrial temperature ranges.

Supervisors Feature Summary

• Integrates a windowed watchdog timer with manual reset capability for robust system monitoring
• Provides a push-pull active-low reset output ensuring valid signals down to 1.0 V supply
• Features low power consumption and high immunity to power supply glitches

Supervisors Applications

• Microprocessor system supervision
• Embedded controller power management
• Industrial equipment voltage monitoring

Supervisors Procurement Notes

Verify the specific suffix ARJZR7 indicates reel packaging when ordering. Confirm the WC26 designation corresponds to the 2.625 V threshold requirement for your design. Check current availability status as distribution may vary. Ensure compatibility with your PCB footprint for the SOT-23-5 package. Validate that the operating temperature range meets your environmental specifications.

Supervisors Selection Notes

Select this component when a fixed 2.625 V threshold is required for single-supply monitoring. Choose the push-pull output configuration if driving logic directly without external pull-ups. Consider the 1.6-second watchdog timeout for slower microcontroller clock speeds. Verify that the 140 ms reset delay aligns with your system startup requirements. Ensure the SOT-23-5 package fits your board space constraints.

Supervisors Part Context

This part belongs to the ADM8322 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and output configurations to suit different application needs. The ADM8322 specifically integrates both voltage supervision and watchdog functions in a small footprint. It is designed for reliability in critical embedded systems requiring continuous power monitoring.

Supervisors Replacement Considerations

ADM8322WB26ARJZR7: Offers identical electrical characteristics but with an active-high push-pull reset output instead of active-low.
