ADM1811-5AKSZ-REEL

Supervisors Overview

The ADM1811-5AKSZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc. It monitors a single input voltage and asserts a reset signal when the supply falls below the specified threshold. The device features an active low, open-drain output with an internal pull-up resistor. Key electrical parameters include a maximum supply voltage of 5.5 V, a typical trip point of 4.62 V, and a reset delay time of 250 ms. It operates within a temperature range of -40°C to +105°C and is housed in a SC-70-3 surface-mount package.

Supervisors Feature Summary

• Monitors a single voltage rail for under-voltage conditions
• Provides an active low reset signal via open-drain output
• Includes internal pull-up resistor for simplified interface
• Operates across extended industrial temperature ranges

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system supervision
• Portable electronic device voltage tracking

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Check current availability as this part may be subject to limited supply or end-of-life restrictions. Ensure storage conditions meet semiconductor handling standards to prevent degradation before assembly.

Supervisors Selection Notes

Select this component when a dedicated supervisor for a 5V rail is required with open-drain output compatibility. Consider the 4.62V trip point accuracy and 250ms delay against system timing requirements. Evaluate the SC-70-3 footprint constraints against PCB layout limitations. Compare against alternatives if manual reset or watchdog functionality is needed, as this model lacks those features.

Supervisors Part Context

This part belongs to the ADM1811 series of microprocessor reset circuits from Analog Devices. It is designed specifically for monitoring 5V supplies in digital systems. The REEL suffix indicates tape-and-reel packaging for automated assembly. It complements other variants in the family that offer different thresholds or output configurations.

Supervisors Replacement Considerations

Direct substitutes include ADM1811-5ARTZ-REEL and ADM1811-5AKSZ-RL7. Verify pinout compatibility and electrical specifications match exactly. Note that some variants may have different packaging formats or slight parameter variations requiring design review.
