ADM1811-10ARTZ-RL7

Supervisors Overview

The ADM1811-10ARTZ-RL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.3 V to 5.5 V and features a fixed reset threshold voltage of 4.35 V. The device provides a push-pull active-low output with a typical reset delay time of 200 ms. It is housed in a compact SOT-23-3 surface-mount package and supports an operating temperature range from -40°C to +85°C. The circuit consumes low quiescent current, making it suitable for battery-powered applications requiring reliable power monitoring.

Supervisors Feature Summary

• Monitors supply voltage against a fixed threshold to generate system reset signals
• Provides manual reset input capability for controlled system initialization
• Features active-low push-pull output driver for direct interface with logic circuits

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-operated electronic devices
• Portable instrumentation systems

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements. Validate pinout compatibility with target PCB footprint. Review datasheet revisions for any functional updates affecting design-in parameters.

Supervisors Selection Notes

Select this component when a fixed 4.35 V threshold is required for system supervision. Consider the SOT-23-3 package for space-constrained designs. Evaluate the 200 ms reset delay against system startup timing requirements. Compare quiescent current specifications against other supervisors if extended battery life is critical. Verify that the active-low output polarity matches the downstream logic interface.

Supervisors Part Context

This part belongs to the ADM1811 series of supervisory circuits designed for voltage monitoring applications. It shares the same package and basic functionality as variants with different threshold voltages, such as the ADM1811-10ARTZ. The suffix RL7 indicates reel packaging configuration. It is distinct from the ADM1817 series which offers adjustable thresholds and different reset delay characteristics.

Supervisors Replacement Considerations

Direct substitutes include ADM1811-10ARTZ (tube packaging) or ADM1811-10ARTZ-REEL7. Cross-reference with ADM1811-xxARTZ-RL7 variants where xx denotes different threshold voltages if the 4.35 V level is not mandatory. Verify pinout compatibility before substitution.
