ADM809MART-REEL7

Supervisors Overview

The ADM809MART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for surface-mount applications in the SOT-23-3 package. It operates within a supply voltage range of 1 V to 5.5 V, consuming a typical quiescent current of 60 uA. The device features a push-pull output and monitors a single input without manual reset or watchdog timer capabilities. It functions reliably across an extended temperature range from -40°C to +125°C. This component belongs to the ADM809 series and is supplied in reel, cut tape, or MouseReel formats.

Supervisors Feature Summary

• Provides voltage supervision with a push-pull output interface
• Operates within a wide supply voltage range of 1 V to 5.5 V
• Supports extended industrial temperature operation from -40°C to +125°C
• Features low quiescent current consumption for power efficiency

Supervisors Applications

• Microprocessor system reset generation
• Battery-powered equipment monitoring
• Portable instrumentation power supervision

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance requirements as the specific variant may not meet standard regulations. Check lead times carefully given limited availability. Ensure packaging format matches production needs. Validate thermal performance against application constraints before integration.

Supervisors Selection Notes

Select this part when a simple, low-power supervisor is required for voltages up to 5.5 V. Consider the fixed threshold characteristics inherent to the MART suffix. Evaluate if the absence of manual reset meets system design requirements. Compare against other ADM809 variants for different threshold options. Ensure the SOT-23-3 package fits the PCB layout constraints.

Supervisors Part Context

Part of the ADM809 family of supervisory circuits offering various threshold options. Shares common architecture with ADM809LARTZ and ADM809SARTZ but differs in specific trip points. Designed for compact designs requiring minimal external components. Competes with similar supervisors from other manufacturers in the PMIC category.
