ADM809-5SAKS-REEL7

Supervisors Overview

The ADM809-5SAKS-REEL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply voltages in embedded systems. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 2.93 V with an accuracy of 1.5%. The device provides a push-pull active-low reset output with a typical reset delay time of 240 ms, ensuring stable system initialization during power-up or brown-out events. It consumes a maximum operating supply current of 60 µA and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a compact SC-70-3 surface-mount case, this component lacks manual reset, watchdog timer, or battery backup switch functionalities.

Supervisors Feature Summary

• Provides precise voltage monitoring for single-channel power supplies
• Generates active-low reset signal upon power failure detection
• Ensures reliable system startup through internal reset timeout control

Supervisors Applications

• Microprocessor system power supervision
• Embedded controller voltage monitoring
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix '5S' indicates the 2.93 V threshold variant when sourcing replacements. Confirm package integrity for SC-70-3 compatibility. Check regional distribution availability as stock may be limited. Ensure environmental compliance documentation matches project requirements.

Supervisors Selection Notes

Select this component for applications requiring a fixed low-voltage threshold with high accuracy. Consider the 240 ms reset delay for timing-sensitive microcontrollers. Evaluate the 60 µA current consumption against battery life requirements. Verify that the absence of a watchdog timer meets system safety standards.

Supervisors Part Context

This part belongs to the ADM809 series of supervisory circuits from Analog Devices. The series offers various threshold options and packages. The '5S' designation specifies the 2.93 V threshold version. The 'REEL7' suffix denotes tape-and-reel packaging for automated assembly processes.

Supervisors Replacement Considerations

Direct substitutes include other ADM809 variants with matching thresholds. Verify pinout compatibility for SC-70-3 packages. Cross-reference reset delay times with target microcontroller specifications.
