ADM812ZARTZ-REEL

Supervisors Overview

The ADM812ZARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor a single power supply input. It operates within a supply voltage range up to 5.5 V and features an active high output type with manual reset capability. The device includes a fixed threshold voltage of 4.63 V and an overvoltage threshold of 4.72 V, ensuring precise supervision. It provides a reset delay time of 560 ms and maintains an accuracy of 1.5%. The component functions in temperatures from -40°C to +85°C, drawing a typical operating supply current of 15 µA. It is housed in an SOT-143-4 package for surface mount installation.

Supervisors Feature Summary

• Provides continuous monitoring of a single voltage rail with a fixed threshold.
• Features an active high output signal compatible with various logic families.
• Includes a manual reset input for controlled system recovery.
• Operates with low quiescent current suitable for battery-powered applications.

Supervisors Applications

• Portable electronic devices requiring reliable power management
• Microprocessor and microcontroller systems needing stable reset signals
• Battery-operated equipment with strict power consumption limits

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as 'REEL' indicates tape-and-reel packaging which may differ from cut-tape availability. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents before integration. Ensure the specific batch matches the required temperature grade and package variant for your design constraints.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with an active high output is required. The fixed 4.63 V threshold suits standard 5 V logic systems. Consider the 560 ms delay for application timing requirements. Verify that the SOT-143-4 package fits the PCB layout constraints and that the manual reset feature aligns with the system control architecture.

Supervisors Part Context

This part belongs to the ADM812 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and output types to accommodate different power supply architectures. The ZARTZ suffix typically denotes specific packaging and temperature range variations within the broader product family, distinguishing it from other pin-compatible or functionally similar variants.

Supervisors Replacement Considerations

Check for direct replacements within the ADM812 series offering identical thresholds and output polarity. Verify pinout compatibility if substituting with other manufacturers' supervisors. Ensure replacement parts meet the same electrical specifications for threshold accuracy, reset delay, and operating current to maintain system stability.
