ADM809SART-REEL7

Supervisors Overview

The ADM809SART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It operates within a supply voltage range of 1 V to 5.5 V and draws a typical quiescent current of 60 uA. The device features a push-pull output configuration without manual reset or watchdog timer capabilities. It is housed in an SOT-23-3 surface-mount package and supports operation across an extended temperature range from -40°C to +125°C. This component belongs to the ADM809 series.

Supervisors Feature Summary

• Provides voltage supervision with a push-pull output interface
• Operates on low supply voltages starting from 1 V
• Suitable for industrial environments with wide temperature tolerance

Supervisors Applications

• Microprocessor system reset generation
• Battery-powered equipment power monitoring
• Portable electronic device voltage supervision

Supervisors Procurement Notes

Verify component authenticity through authorized channels as this part is marked as obsolete. Confirm specific threshold voltage requirements against application needs since variants exist within the series. Check RoHS compliance status carefully due to the 'N' designation in available records. Ensure packaging format matches inventory availability constraints.

Supervisors Selection Notes

Select this component when a simple, low-power supervisor is required for single-rail monitoring. Consider the fixed threshold characteristics inherent to the specific suffix variant. Evaluate the SOT-23-3 footprint compatibility during PCB layout. Compare against newer Analog Devices offerings if long-term supply assurance is critical for the design lifecycle.

Supervisors Part Context

This part belongs to the ADM809 family of reset generators. Similar parts include the ADM809TAKSZ and ADM809ZARTZ, which share the same core functionality but differ in threshold voltages and packages. The ADM810 series offers comparable performance with different timing characteristics. These components are generally used in conjunction with microcontrollers and digital logic circuits.
