ADM1815-R22AKSZ-R7

Supervisors Overview

The ADM1815-R22AKSZ-R7 is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor system voltage levels. It operates within a supply voltage range of 1.6V to 5.5V and features a fixed reset threshold voltage of 2.2V. The device utilizes an SC-70-3 surface-mount package for compact integration. Key electrical parameters include a maximum reset delay time of 200ms and a typical quiescent current of 4µA. It provides a push-pull output configuration and lacks manual reset or watchdog timer functionalities, ensuring reliable power management in low-voltage applications.

Supervisors Feature Summary

• Monitors single input voltage with a fixed threshold
• Provides active-low reset signal via push-pull output
• Operates with ultra-low quiescent current consumption

Supervisors Applications

• Portable electronic devices requiring battery monitoring
• Embedded systems needing brown-out protection
• Microcontroller power supply supervision circuits

Supervisors Procurement Notes

Verify the specific suffix 'R22' confirms the 2.2V threshold variant during procurement. Confirm the 'RL7' packaging designation matches required reel specifications. Ensure compatibility with SC-70-3 footprint constraints. Cross-reference the manufacturer datasheet for latest revision status before finalizing orders.

Supervisors Selection Notes

Select this component when a fixed 2.2V threshold is required for voltage supervision. Consider the SC-70-3 package size for space-constrained designs. Evaluate the 4µA quiescent current against system power budget requirements. Ensure the push-pull output capability meets interface requirements for the downstream logic.

Supervisors Part Context

This part belongs to the ADM1815 series of voltage supervisors from Analog Devices. It is distinct from other variants in the family that offer adjustable thresholds or different reset delays. The series is categorized under PMIC - Power Management ICs, specifically focusing on supervisory circuits for maintaining system integrity during power fluctuations.

Supervisors Replacement Considerations

Direct substitutes may include other ADM1815 variants with compatible thresholds. Verify pinout compatibility with SC-70-3 packages. Check if alternative manufacturers offer equivalent 2.2V threshold supervisors with similar quiescent current profiles.
