ADM1817-5ART-REEL

Supervisors Overview

The ADM1817-5ART-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc. It functions as a reset generator IC designed to monitor a single power supply input. The device features a push-pull output configuration and operates within a maximum supply voltage of 5.5 V. It provides a fixed threshold voltage of 5 V for supervision, with an overvoltage threshold of 3.15 V. The component includes a reset delay time of 250 ms and consumes a typical operating supply current of 16 uA. It is housed in a SOT-23-3 package and supports surface mount installation. The operational temperature range spans from -40 C to +105 C.

Supervisors Feature Summary

• Provides automatic system reset generation upon detection of power supply anomalies
• Features a compact three-terminal surface-mount package design
• Delivers a push-pull output signal without requiring manual reset functionality

Supervisors Applications

• Microprocessor system power monitoring
• Battery-powered device voltage supervision
• Embedded controller reset generation

Supervisors Procurement Notes

Verify the exact suffix designation against official documentation, as variations such as RL7 or REEL may indicate different packaging formats like tape and reel or cut tape. Confirm availability status, as this specific part number may be discontinued or subject to limited supply constraints depending on the manufacturer's current production lifecycle. Ensure compatibility with existing PCB footprints before procurement.

Supervisors Selection Notes

Select this component when a simple, low-power voltage supervisor is required for systems operating near 5 V logic levels. The fixed 5 V threshold makes it suitable for standard digital circuits. Consider the SOT-23-3 package size for space-constrained designs. Verify that the 250 ms reset delay meets the timing requirements of the target microcontroller or processor during power-up sequences.

Supervisors Part Context

This component belongs to the ADM1817 series of supervisory circuits from Analog Devices. The series offers various threshold voltages including 2.5 V, 3 V, 3.3 V, and 5 V options. These devices are designed for cost-effective power management solutions in consumer and industrial electronics where reliable reset signaling is critical for system stability.

Supervisors Replacement Considerations

Check for direct substitutes within the ADM1817 family with matching threshold voltages. Verify pinout compatibility with the SOT-23-3 package. Ensure replacement parts maintain similar operating temperature ranges and supply current specifications.
