ADM803LAKSZ-REEL7

Supervisors Overview

The ADM803LAKSZ-REEL7 is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 4.63 V. The device provides an open-drain or push-pull output type with a reset delay time of 240 ms. It does not include manual reset, watchdog timer, or battery backup switch functions. The component is housed in an SC-70-3 package and supports surface mount installation.

Supervisors Feature Summary

• Provides power supply monitoring with a fixed threshold voltage for reliable system supervision
• Offers flexible output configuration supporting both open-drain and push-pull modes
• Ensures stable reset generation through a defined delay period after voltage recovery

Supervisors Applications

• Microprocessor supervisor circuits requiring voltage monitoring
• Power supply support systems for embedded controllers
• Electronic devices needing automated reset generation upon power failure

Supervisors Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm package and tape/reel specifications. Confirm RoHS compliance status and manufacturing origin via the latest datasheet. Check for any specific handling requirements related to moisture sensitivity level. Ensure compatibility with existing PCB footprint designs before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-input voltage supervision. Consider the SC-70-3 package size for space-constrained applications. Evaluate the need for open-drain versus push-pull outputs based on downstream logic interface requirements. Verify that the absence of manual reset and watchdog features aligns with system design constraints.

Supervisors Part Context

This component belongs to the ADM803 series of voltage supervisory circuits from Analog Devices. It is designed for low-cost, high-reliability power management applications. The REEL7 suffix indicates it is supplied in a tape and reel format suitable for automated assembly processes. It serves as a fundamental building block for ensuring system stability during power transitions.

Supervisors Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully. Ensure any substitute maintains the 4.63 V threshold and compatible package dimensions.
