ADM809-5LART-REEL7

Supervisors Overview

The ADM809-5LART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply rails. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 5.0 V with an overvoltage threshold of 5.25 V. The device provides a push-pull output type and includes a reset delay time of 240 ms. It functions without manual reset, watchdog timer, or battery backup switching capabilities. The component exhibits an accuracy of 1.5% and draws a working supply current of 60 uA. It is housed in a SOT-23-3 package and supports surface mount installation across a temperature range of -40 C to +125 C.

Supervisors Feature Summary

• Provides active low reset signal generation via push-pull output for reliable logic interfacing
• Monitors single input voltage channel with factory-set threshold levels for simplified design integration
• Operates with low quiescent current consumption suitable for power-sensitive applications

Supervisors Applications

• Microprocessor system power supervision
• Portable equipment voltage monitoring
• Battery-powered device reset generation

Supervisors Procurement Notes

Verify the specific suffix configuration against official Analog Devices documentation to ensure correct threshold voltage and package variant alignment. Confirm RoHS compliance status through manufacturer datasheets prior to procurement. Cross-reference ordering part numbers with authorized distributors to avoid obsolete or discontinued stock variations. Validate environmental operating ranges match application requirements before finalizing purchase orders.

Supervisors Selection Notes

Select this component when a fixed 5.0 V threshold is required for single-supervision tasks. Ensure the SOT-23-3 package fits the PCB layout constraints. Consider the 240 ms reset delay duration relative to system startup timing requirements. Verify that the absence of manual reset and watchdog features aligns with the target application's safety and control logic needs.
