ADM824LYRJZ-REEL7

Supervisors Overview

The ADM824LYRJZ-REEL7 is a supervisory circuit manufactured by Analog Devices Inc., designed for voltage monitoring applications. It features a watchdog timer and operates within a supply voltage range of 1 V to 5.5 V. The device monitors a single input with a threshold voltage of 4.63 V and an overvoltage threshold of 4.7 V. It provides a push-pull output type and includes a reset delay time of 280 ms. The component functions without manual reset or chip enable signals, drawing a typical operating supply current of 24 uA. It is housed in an SOT-23-5 package suitable for surface mount installation.

Supervisors Feature Summary

• Integrated watchdog timer functionality for system reliability monitoring
• Push-pull output configuration for robust signal driving
• Low power consumption with minimal operating supply current
• Single-input voltage supervision with defined threshold levels

Supervisors Applications

• Microprocessor system reset circuits
• Battery-powered device supervision
• Embedded system watchdog monitoring
• Voltage level detection in portable electronics

Supervisors Procurement Notes

Verify the specific suffix REEL7 indicates tape and reel packaging when ordering. Confirm the exact threshold voltage requirements match the 4.63 V specification provided in the datasheet. Ensure the SOT-23-5 footprint aligns with the target PCB design. Check for any RoHS compliance documentation if required by project specifications. Validate that the operating temperature range meets environmental conditions.

Supervisors Selection Notes

Select this component when a low-power supervisory circuit with integrated watchdog capabilities is required. It is suitable for applications needing precise voltage monitoring with a fixed threshold. Consider the SOT-23-5 package size for space-constrained designs. Evaluate the 24 uA supply current against battery life requirements. Ensure the push-pull output interface is compatible with the downstream logic inputs.

Supervisors Part Context

This part belongs to the ADM824 series of supervisory circuits from Analog Devices. It is distinct from operational amplifiers or analog switches sharing similar prefixes. The device focuses on power management and system protection rather than signal amplification or switching. It complements other PMIC offerings by providing dedicated voltage supervision and timing functions.
