ADM809JAKSZ-REEL7

Supervisors Overview

The ADM809JAKSZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply rails in microprocessor systems. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 3.11 V with an accuracy of 1.5%. The device provides a push-pull output and includes a reset delay time of 240 ms. It functions without manual reset, watchdog timer, or battery backup switching capabilities. The component supports surface mount installation in an SC-70-3 package and maintains operation across a temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides precise voltage supervision with high accuracy for reliable system monitoring
• Features a push-pull output configuration for direct interface compatibility
• Operates effectively across extended industrial temperature ranges

Supervisors Applications

• Microprocessor power supply monitoring
• Voltage supervision in embedded systems

Supervisors Procurement Notes

Verify the specific suffix JAKSZ against official Analog Devices documentation to confirm exact threshold voltage and package specifications. Ensure compliance with RoHS requirements and check regional availability restrictions as distribution status may vary. Confirm that the reel packaging aligns with automated assembly processes.

Supervisors Selection Notes

Select this component when a fixed threshold voltage near 3.11 V is required for single-input monitoring. Consider the SC-70-3 package size for space-constrained designs. Evaluate the 240 ms reset delay against system startup timing requirements. Verify that the absence of a watchdog timer meets the application's safety needs.

Supervisors Part Context

This part belongs to the ADM809 series of supervisory circuits from Analog Devices. It is categorized under PMIC - Power Management ICs and specifically Voltage Supervisory types. The device complements other components in power management chains by ensuring stable operation through continuous voltage monitoring.

Supervisors Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference parameters such as threshold voltage, package type, and operating temperature range to ensure functional equivalence.
