ADM809JAKSZ-REEL

Supervisors Overview

The ADM809JAKSZ-REEL is a voltage supervisory circuit from Analog Devices, designed to monitor power supply rails in microprocessor systems. It operates within a supply voltage range of 1 V to 5.5 V and features a push-pull output. The device monitors a single input with a threshold voltage of 4 V and an overvoltage threshold of 4.06 V. It provides a fixed reset delay time of 240 ms and maintains accuracy within 1.5%. The component draws a working supply current of 60 uA and functions reliably across an operating temperature range of -40°C to +125°C. It is housed in an SC-70-3 surface-mount package.

Supervisors Feature Summary

• Provides automatic reset signals during power-up, power-down, and undervoltage conditions
• Features a compact SC-70-3 surface-mount package for space-constrained designs
• Delivers a push-pull output for direct interface with digital logic

Supervisors Applications

• Microprocessor system power monitoring
• Battery-powered equipment voltage supervision
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix JAKSZ against the target design requirements to ensure correct threshold voltage and package compatibility. Confirm RoHS compliance status as indicated in official documentation before procurement. Check for any product change notices or lifecycle status updates directly from Analog Devices to ensure long-term availability and manufacturing consistency.

Supervisors Selection Notes

Select this component when a 4 V threshold and 240 ms delay are required for single-channel voltage monitoring. Consider the SC-70-3 package size for board space limitations. Ensure the application voltage stays within the 1 V to 5.5 V operational range. Verify that the 60 uA quiescent current meets the system's power budget constraints.
