ADM1815-5ART-REEL7

Supervisors Overview

The ADM1815-5ART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor system power integrity. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 5 V for accurate power level detection. The device provides a reset signal with a typical delay time of 200 ms, ensuring stable system initialization during power-up or brown-out events. Packaged in a compact SOT-23-5 surface-mount format, it supports open-drain or push-pull output configurations. The component is intended for applications requiring reliable voltage monitoring without manual reset capabilities or watchdog timer functions.

Supervisors Feature Summary

• Monitors single input voltage supply for under-voltage conditions
• Generates active-low reset signal upon threshold violation
• Provides configurable output drive strength via external resistor
• Operates independently without requiring external timing components

Supervisors Applications

• Portable electronic devices requiring battery voltage supervision
• Embedded systems needing reliable power-on reset sequencing
• Industrial control units monitoring main power rails
• Communication equipment ensuring stable logic operation

Supervisors Procurement Notes

Verify the exact suffix configuration against official Analog Devices documentation to confirm output type and package variant. Confirm availability status through authorized distributors as supply constraints may apply. Ensure compatibility with target PCB footprint and thermal requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 5 V threshold is required for system supervision. Consider the SOT-23-5 package size for space-constrained designs. Evaluate the need for push-pull versus open-drain outputs based on downstream logic interface requirements. Verify operating temperature range alignment with application environment specifications.

Supervisors Part Context
