ADM823ZYKS-R7

Supervisors Overview

The ADM823ZYKS-R7 is a single-channel power supply management circuit manufactured by Analog Devices Inc. It functions as a voltage supervisor with an integrated reset mechanism, housed in a compact SC-70 (SOT-353) package featuring five pins. The device monitors a single input line and provides a push-pull output. Key electrical parameters include a fixed reset threshold voltage of 2.32V and a reset delay time of 140ms. It operates within a supply voltage range up to 5.5V and supports an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates voltage supervision and reset generation in a single channel
• Features a fixed reset threshold for precise monitoring without external components
• Provides active low push-pull output for direct logic interface compatibility

Supervisors Applications

• Portable battery-powered equipment requiring low standby current
• Microprocessor system reset circuits
• Battery backup switching systems
• Watchdog timer applications

Supervisors Procurement Notes

Verify the specific suffix 'R7' indicates tape and reel packaging configuration. Confirm the manufacturer source, as Rochester Electronics may distribute this part. Ensure the component meets RoHS compliance standards if required by your assembly process. Check for any obsolescence notices or lifecycle status updates directly from the supplier before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 2.32V threshold is appropriate for the monitored rail. The SC-70 package is suitable for space-constrained designs. Consider the 140ms reset delay duration relative to the target system's startup requirements. Verify that the single-channel architecture meets the monitoring needs without requiring additional supervisory ICs.

Supervisors Part Context

This part belongs to the ADM823 series of micro-power supervisors. It is designed for applications where low quiescent current and small footprint are critical. The series typically includes variants with different thresholds and packages, offering flexibility for various voltage monitoring scenarios in consumer and industrial electronics.

Supervisors Replacement Considerations

Check for ADM823 variants with different threshold voltages if the 2.32V level is unsuitable. Verify pinout compatibility with alternative supervisors in the same package family. Ensure equivalent reset delay characteristics are maintained for system stability.
