ADM809SAKS-REEL

Supervisors Overview

The ADM809SAKS-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply rails in microprocessor systems. It operates within a supply voltage range up to 5.5 V and features a push-pull output driver. The device provides a reset delay time of 240 ms and maintains an operating supply current of 60 uA. It is housed in an SC-70-3 surface-mount package and supports a wide industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides precise voltage supervision with high accuracy for reliable system reset generation
• Features a compact SC-70-3 surface-mount package suitable for space-constrained designs
• Operates with low quiescent current to minimize power consumption in battery-powered applications

Supervisors Applications

• Microprocessor system power monitoring
• Battery-operated electronic devices
• Portable instrumentation circuits

Supervisors Procurement Notes

Verify the exact threshold voltage specification, as the 'S' suffix typically denotes a specific fixed value (e.g., 2.93 V) distinct from other variants in the ADM809 series. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may be restricted. Ensure the SC-70-3 package footprint matches your PCB design requirements before finalizing procurement.

Supervisors Selection Notes

Select this component when a fixed threshold voltage near 2.93 V is required for 3V logic systems. Compare the 240 ms reset delay against system startup timing requirements. Consider the 60 uA supply current for low-power constraints. Verify that the push-pull output capability meets the drive requirements of the connected processor reset pin without additional external components.

Supervisors Part Context

This part belongs to the ADM809 family of simple voltage supervisors from Analog Devices. These devices are engineered to provide robust reset signals for digital systems. The ADM809 series offers various threshold options and packaging styles to accommodate different voltage levels and form factor constraints across industrial and consumer electronics applications.

Supervisors Replacement Considerations

ADM809SAKSZ-REEL7 is a documented equivalent variant within the same product line.
