ADM809ZAKSZ-REEL

Supervisors Overview

The ADM809ZAKSZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of up to 5.5 V and features a push-pull output type. The device monitors a single input with a threshold voltage of 2.5 V and an overvoltage threshold of 2.35 V. It provides a reset delay time of 840 ms and consumes a working power current of 60 uA. The component is housed in an SC-70-3 package and supports surface mount installation. It functions without manual reset, watchdog timer, or battery backup switch capabilities. The operational temperature range spans from -40 C to +125 C.

Supervisors Feature Summary

• Provides voltage supervision for microprocessor systems with a dedicated reset output.

Supervisors Applications

• Microprocessor system monitoring

Supervisors Procurement Notes

Verify the exact part number suffix against official documentation, as variations such as REEL7 indicate specific packaging configurations. Confirm availability status directly with authorized distributors, as this component may be discontinued or subject to regional sales restrictions. Ensure that the SC-70-3 package dimensions and pinout match the design requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 2.5 V threshold is required for system supervision. Consider the 840 ms reset delay duration to ensure compatibility with target processor startup times. Evaluate the 60 uA quiescent current consumption against power budget constraints. Verify that the SC-70-3 package size fits within the available PCB area.

Supervisors Part Context

This part belongs to the ADM809 series of supervisory circuits from Analog Devices. It is designed for applications requiring reliable voltage monitoring in compact form factors. The series typically offers various threshold options to accommodate different logic levels and supply voltages commonly found in embedded systems.

Supervisors Replacement Considerations

Direct substitutes include other ADM809 variants with matching 2.5 V thresholds and SC-70-3 packages. Cross-reference specifications for reset delay and current consumption to ensure functional equivalence.
