ADM809-5LARTZ-REEL

Supervisors Overview

The ADM809-5LARTZ-REEL is a voltage supervisory circuit from Analog Devices, designed for microprocessor systems. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 4.63 V with an accuracy of 1.5%. The device provides a push-pull reset output with a fixed delay of 240 ms. It consumes 60 uA of operating current and lacks manual reset or watchdog timer functions. The component is available in SOT-23-3 packaging and supports operation across temperatures from -40 C to +125 C.

Supervisors Feature Summary

• Monitors power supply voltage to ensure system stability
• Provides active reset signal upon voltage deviation
• Operates with low quiescent current consumption

Supervisors Applications

• Microprocessor system power monitoring
• Voltage supervision in embedded controllers
• Power-on reset generation for digital circuits

Supervisors Procurement Notes

Verify the exact suffix (REEL vs RL7) against the manufacturer's current datasheet, as packaging designations may vary. Confirm RoHS compliance status directly with Analog Devices or authorized distributors, as historical data indicates detailed verification is required. Ensure the specific batch matches the intended thermal and electrical specifications for your application environment.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-input voltage monitoring. It is suitable for applications needing a simple push-pull output without manual reset capabilities. Consider the SOT-23-3 package size and the 240 ms delay time relative to your system's startup requirements and noise immunity needs.
