ADM809TAKSZ-REEL7

Supervisors Overview

The ADM809TAKSZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor supervision in SC-70 packages. It features a push-pull output and monitors a single input with a threshold voltage of 3.08 V and an overvoltage threshold of 3.11 V. The device operates within a supply voltage range up to 5.5 V, maintaining accuracy of 1.5%. It includes a reset delay time of 240 ms and consumes 60 uA of operating current. The component supports surface mount installation and functions reliably across temperatures from -40 C to +125 C.

Supervisors Feature Summary

• Provides precise voltage monitoring with factory-set thresholds for reliable system supervision
• Features a compact SC-70-3 package suitable for space-constrained surface mount applications
• Delivers a push-pull output signal without requiring manual reset or watchdog timer functionality

Supervisors Applications

• Microprocessor power supply monitoring
• Voltage supervision in portable electronic devices
• System reset generation in embedded controllers

Supervisors Procurement Notes

Verify the exact suffix TAKSZ to confirm the specific 3.08 V threshold voltage, as variations exist within the ADM809 family. Confirm availability status due to limited supply indications. Ensure compatibility with SC-70-3 footprint requirements during procurement planning.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for single-input voltage supervision. Consider the 240 ms reset delay and 60 uA current consumption against system timing and power constraints. Verify that the push-pull output configuration meets interface requirements compared to open-drain alternatives.

Supervisors Part Context

This part belongs to the ADM809 series of voltage supervisors from Analog Devices. It shares common characteristics such as low power consumption and compact packaging with other variants in the family, differing primarily in its specific threshold voltage setting and output configuration details defined by the model code.

Supervisors Replacement Considerations

Substitute parts must match the 3.08 V threshold, SC-70-3 package, and push-pull output type. Verify equivalent electrical specifications including reset delay and operating temperature range before implementation.
