ADM803ZAKS-REEL7

Supervisors Overview

The ADM803ZAKS-REEL7 is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed reset threshold voltage of 2.32 V with an accuracy of 1.5%. The device provides a push-pull output type and includes a reset delay time of 240 ms. It does not support manual reset, watchdog timer, or battery backup switching functions. The component is designed for surface mount installation in SC-70-3 packages and supports operation across a temperature range from -40 °C to +125 °C.

Supervisors Feature Summary

• Provides open drain microprocessor supervision with a fixed threshold voltage
• Features push-pull output configuration for direct logic interface
• Includes a defined reset delay time to ensure stable power-up sequencing

Supervisors Applications

• Microprocessor system power monitoring
• Voltage supervision in embedded controllers
• Power management circuits requiring fixed threshold detection

Supervisors Procurement Notes

Verify the specific suffix ZAKS against the official datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status as indicated in current documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Ensure the ordering part number matches the required pinout and electrical characteristics exactly.

Supervisors Selection Notes

Select this component when a fixed 2.32 V threshold is required for systems operating between 1 V and 5.5 V. The push-pull output eliminates the need for external pull-up resistors compared to open-drain variants. Consider the 240 ms reset delay for applications requiring extended power-on stabilization periods before releasing the reset signal.

Supervisors Part Context

This part belongs to the ADM803 series of supervisory circuits from Analog Devices. It is distinct from other ADM8xx variants by its specific threshold voltage and output configuration. The REEL7 designation indicates it is supplied in a standard tape and reel format suitable for automated surface-mount assembly processes.
