ADM809-5SARTZ-RL7

Supervisors Overview

The ADM809-5SARTZ-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply voltages in microprocessor systems. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 2.93 V with an accuracy of 1.5%. The device provides a push-pull output and includes a fixed reset delay time of 240 ms. It functions without manual reset, watchdog timer, or battery backup switch capabilities. The component supports single-input monitoring and draws a working supply current of 60 uA. It is available in an SOT-23-3 package and operates across a temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Provides reset output during power-up, power-down, and brown-out conditions
• Features internal timer for fixed 240 ms reset delay upon power application
• Delivers push-pull output signal for direct interface with logic circuits

Supervisors Applications

• Microprocessor system power supply monitoring
• Voltage supervision in embedded control units
• Brown-out detection in portable electronic devices

Supervisors Procurement Notes

Verify the specific suffix '5' indicates the 2.93 V threshold variant when sourcing replacements. Confirm package integrity for SOT-23-3 components. Check manufacturer documentation for any obsolescence notices or lifecycle status changes. Ensure compatibility with existing board layouts requiring this specific pinout and electrical characteristics.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for system supervision. Consider the 60 uA quiescent current for low-power applications. Verify that the 240 ms delay meets system startup timing requirements. Ensure the operating temperature range covers the intended environmental conditions.
