ADM1816-10ART-RL7

Supervisors Overview

The ADM1816-10ART-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features a fixed reset threshold voltage of 4.63 V, corresponding to the '10' suffix designation. The device provides a push-pull active-low reset output with a typical reset delay time of 200 ms. It includes manual reset functionality via an external input pin and supports operation across an industrial temperature range from -40°C to +85°C. Packaged in a compact SOT-23-5 surface-mount case, it draws a maximum quiescent current of 20 µA.

Supervisors Feature Summary

• Integrates watchdog timer functionality for system reliability monitoring
• Provides manual reset capability through dedicated external input pin
• Features low power consumption suitable for battery-operated applications

Supervisors Applications

• Embedded systems requiring reliable power supervision
• Microcontroller-based designs needing watchdog protection
• Portable electronic devices with limited power budgets

Supervisors Procurement Notes

Verify the specific suffix 'ART' confirms the SOT-23-5 package and reel packaging configuration. Confirm the '10' suffix matches the required 4.63 V threshold voltage for your design. Ensure compatibility with the specified operating temperature range and check for any recent lifecycle notifications regarding availability or obsolescence status before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required alongside integrated watchdog and manual reset features. Compare against adjustable threshold variants if precise voltage tracking is needed. Consider the SOT-23-5 footprint constraints and verify that the 200 ms reset delay aligns with system startup timing requirements. Evaluate alternative packages if space or thermal constraints differ from standard SOT-23-5 specifications.

Supervisors Part Context

This part belongs to the ADM1816 series of voltage supervisors from Analog Devices. The series offers various threshold voltages and package options to suit different application needs. The ADM1816-10ART-RL7 specifically targets applications requiring a fixed high-voltage threshold with integrated safety features like watchdog timers and manual resets in a small form factor.

Supervisors Replacement Considerations

Check Analog Devices documentation for direct pin-compatible replacements within the ADM1816 family with different thresholds. Verify functional equivalence for watchdog and manual reset features when considering cross-brand alternatives. Ensure voltage ranges and package dimensions match exactly to avoid redesign efforts.
