ADM803TAKSZ-REEL7

Supervisors Overview

The ADM803TAKSZ-REEL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 4.38 V. The device provides an open drain output with a reset delay time of 240 ms. Packaged in an SC-70-3 surface-mount format, it monitors one input without manual reset or watchdog timer capabilities. The component supports operation across temperatures from -40°C to +125°C.

Supervisors Feature Summary

• Provides voltage supervision for single-input monitoring applications
• Features open drain output configuration for flexible interfacing
• Designed for surface-mount installation in compact SC-70-3 packages

Supervisors Applications

• Microprocessor system power monitoring
• Embedded controller voltage supervision
• Industrial control board reset management

Supervisors Procurement Notes

Verify the specific suffix 'TAKSZ' against official Analog Devices documentation to confirm pinout and electrical characteristics match design requirements. Confirm availability status as distribution channels may indicate limited stock or special order conditions. Ensure the reel packaging specification aligns with automated assembly equipment capabilities. Cross-reference the datasheet revision date to validate parameter accuracy for current production cycles.

Supervisors Selection Notes

Select this component when a fixed 4.38 V threshold is required for systems operating near 5 V logic levels. The open drain output necessitates external pull-up resistors, which must be accounted for in circuit design. Consider the 240 ms reset delay duration relative to processor startup times. Evaluate the SC-70-3 package size constraints against PCB layout limitations before finalizing the bill of materials.

Supervisors Part Context

This part belongs to the ADM803 series of supervisory circuits from Analog Devices. It shares architectural similarities with other devices in the family but differs in threshold voltage and output type specifications. The series targets applications requiring reliable power management without complex programmable features. Understanding the broader ADM80x lineup aids in identifying alternative parts with varying thresholds or output configurations if this specific variant does not meet all system requirements.
