ADM809RARTZ-REEL7

Supervisors Overview

The ADM809RARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply integrity in electronic systems. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 2.63 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 a minimum operating voltage of 1 V and draws a working supply current of 60 uA. It is housed in an SOT-23-3 package and rated for operation between -40 C and +125 C.

Supervisors Feature Summary

• Features a push-pull output structure for direct interface with digital logic.
• Operates over an extended industrial temperature range from -40 C to +125 C.
• Designed for low power consumption with a working supply current of 60 uA.

Supervisors Applications

• Microprocessor system reset generation
• Portable equipment power management
• Battery-powered consumer electronics

Supervisors Procurement Notes

Verify the specific suffix 'R' indicates the 2.63 V threshold variant when sourcing replacements. Confirm RoHS compliance status as documentation may vary by production batch. Check for obsolescence notices since related variants show discontinued status. Ensure the SOT-23-3 footprint matches the target PCB design. Validate that the absence of manual reset functionality aligns with the system requirements.

Supervisors Selection Notes

Select this component when a precise 2.63 V monitoring level is required for single-input supervision. Consider the 240 ms reset delay to ensure stable power-up sequences for connected logic. Evaluate the 60 uA quiescent current against strict battery life constraints. Verify that the push-pull output drive capability meets the input requirements of the downstream microcontroller or FPGA.

Supervisors Part Context

This part belongs to the ADM809 series of voltage supervisors from Analog Devices. The series offers various threshold voltages determined by the middle letter code, such as 'J' for 4 V and 'L' for 4.63 V. The 'R' designation specifically sets the trip point at 2.63 V. These devices are commonly used in portable applications where space and power efficiency are critical design parameters.
