ADM1811-5AKS-REEL

Supervisors Overview

The ADM1811-5AKS-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc. It functions as a reset generator IC designed to monitor system power rails. The component utilizes an SMD/SMT installation style within an SC-70-3 package. It features a single monitored input with a push-pull output type and lacks manual reset, watchdog timer, or battery backup switch capabilities. The device operates with a maximum supply voltage of 5.5 V and provides a fixed reset delay time of 250 ms. It supports threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V.

Supervisors Feature Summary

• Provides automated system reset generation upon detection of under-voltage conditions
• Features a compact surface-mount package suitable for space-constrained designs
• Delivers a defined reset pulse duration following power-up or fault recovery

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset generation
• Portable electronic device power management

Supervisors Procurement Notes

Verify current availability status through authorized distributors as this specific reel variant may be subject to limited supply or discontinuation. Confirm the exact suffix matches project requirements. Ensure RoHS compliance documentation aligns with regional regulations. Validate package orientation and pinout against schematic definitions prior to procurement.

Supervisors Selection Notes

Select this component when a simple, low-pin-count supervisor is required for single-rail monitoring. The fixed 250 ms delay suits applications tolerant of standard startup times. Verify that the available threshold options cover the target rail voltage. Consider the SC-70-3 footprint constraints during PCB layout planning.

Supervisors Part Context
