ADM809LAKSZ-REEL7

Supervisors Overview

The ADM809LAKSZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It operates within a supply voltage range of 1 V to 5.5 V and features a 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 supports overvoltage detection at 4.7 V. The component is housed in an SC-70-3 package, suitable for surface mount installation, and functions reliably across a temperature range of -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 for space-constrained designs
• Includes overvoltage detection capability to protect against input rail anomalies

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered electronic devices
• Portable instrumentation systems

Supervisors Procurement Notes

Verify the specific suffix 'LAKSZ' to confirm the 4.63 V threshold and SC-70-3 packaging configuration. Confirm RoHS compliance status through official documentation. Check current availability as distribution channels may indicate limited stock or discontinuation status. Ensure the reel quantity matches production requirements before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a 4.63 V threshold is required for single-rail supervision. The push-pull output drives loads directly without external pull-ups. Consider the 60 uA quiescent current for low-power applications. Verify that the SC-70-3 footprint fits the PCB layout constraints. Ensure the operating temperature range meets the environmental conditions of the target application.

Supervisors Part Context

This part belongs to the ADM809 series of microprocessor supervisors from Analog Devices. The series offers various threshold voltages and package options to suit different design needs. The ADM809LAKSZ variant specifically targets applications requiring a 4.63 V trip point in a small outline transistor package format.

Supervisors Replacement Considerations

Check for other ADM809 variants with similar thresholds but different packages if pin compatibility is not critical. Verify functional equivalence with other single-channel supervisors offering push-pull outputs and comparable reset delays.
