ADM809LAKS-REEL7

Supervisors Overview

The ADM809LAKS-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply rails. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed threshold voltage of 4.63 V with an accuracy of 1.5%. The device provides a push-pull output and includes a reset delay time of 240 ms. It consumes a typical operating supply current of 60 uA and lacks manual reset, watchdog timer, or battery backup switch functions. The component is housed in an SC-70-3 package and supports operation from -40°C to +125°C.

Supervisors Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability of direct substitutes such as the ADM809LAKSZ-REEL7 variant. Ensure that the SC-70-3 package dimensions align with existing PCB footprints. Validate that the 4.63 V threshold meets the target system requirements without modification.

Supervisors Selection Notes

Select this component when a fixed 4.63 V supervisory threshold is required for systems powered between 1 V and 5.5 V. Consider the 60 uA quiescent current for battery-sensitive designs. The SC-70-3 package offers space efficiency for compact applications. Note that manual reset and watchdog functionalities are not included in this specific variant.

Supervisors Part Context

This component belongs to the ADM809 series of voltage supervisors from Analog Devices. The series focuses on reliable power management for microprocessors and memory devices. Variants differ primarily in threshold voltages and package types, such as SOT-23-3 or SC-70-3. The ADM809LAKS-REEL7 specifically utilizes the smaller SC-70-3 form factor.

Supervisors Replacement Considerations

The ADM809LAKSZ-REEL7 is listed as a direct substitute. Verify pin compatibility and electrical specifications before substitution.
