ADM803LAKSZ-REEL

Supervisors Overview

The ADM803LAKSZ-REEL7 is a single-channel power supply support circuit manufactured by Analog Devices Inc. It operates within a maximum supply voltage of 5.5 V and features an open-drain or push-pull output type. The device monitors one input with a reset threshold voltage of 4.63 V and an overvoltage threshold of 4.7 V. It provides a fixed reset delay time of 240 ms without manual reset or watchdog timer functionality. The accuracy is specified at 1.5%, and the operating supply current is 35 uA. The component functions across a temperature range from -40 °C to +125 °C and is housed in an SC-70-3 package.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed 4.63 V threshold for reliable system monitoring
• Offers flexible output configuration supporting both open-drain and push-pull modes
• Ensures stable operation across extended industrial temperature ranges up to 125 °C

Supervisors Applications

• Microprocessor supervisor circuits requiring voltage monitoring
• Power supply support systems for embedded controllers
• Industrial control applications needing extended temperature stability

Supervisors Procurement Notes

Verify the specific suffix designation, as the provided data references ADM803LAKSZ-REEL7 while the model query specifies ADM803LAKSZ-REEL. Confirm package compatibility and RoHS compliance status directly with the manufacturer or authorized distributors. Ensure that the selected variant matches the required output type and threshold specifications for the target application design.

Supervisors Selection Notes

Select this component when a low-power supervisory circuit with a fixed 4.63 V threshold is required. Consider the 35 uA operating current for battery-sensitive designs. Verify that the SC-70-3 package fits the board space constraints. Ensure the application does not require manual reset or watchdog timer features, as these are absent in this specific part number.

Supervisors Part Context

This component belongs to the ADM803 series of voltage supervisory circuits from Analog Devices. It is designed for power management applications where reliable reset generation is critical. The series typically includes variants with different thresholds and packages, but this specific part is characterized by its 4.63 V threshold and compact surface-mount packaging suitable for dense PCB layouts.

Supervisors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other ADM803 series variants only if electrical parameters such as threshold voltage and output type match exactly.
