ADM823MYKSZ-R7

Supervisors Overview

The ADM823MYKSZ-R7 is a single-channel voltage supervisor integrated circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes a typical operating current of 24 µA. The device features a fixed reset threshold voltage of 2.32 V with an accuracy of 2.5%. It provides a push-pull output and includes a manual reset input capability. The component supports a watchdog timer function and offers a reset delay time of 280 ms. It is housed in a compact SC-70-5 surface-mount package and is rated for operation between -40 °C and +125 °C.

Supervisors Feature Summary

• Integrated watchdog timer functionality for system reliability monitoring
• Manual reset input allows external control over the reset state
• Push-pull output driver ensures robust signal integrity
• Low power consumption suitable for battery-operated applications

Supervisors Applications

• Microprocessor reset circuits
• Battery-powered portable devices
• Industrial control systems requiring voltage supervision
• Embedded systems with watchdog requirements

Supervisors Procurement Notes

Verify the specific suffix 'R7' indicates tape and reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., noting that Rochester Electronics may distribute reconditioned versions of this part. Ensure the SC-70-5 package matches your PCB footprint design. Check RoHS compliance status if required by your manufacturing standards. Validate the 2.32 V threshold specification against your system's voltage monitoring needs.

Supervisors Selection Notes

Select this component when a fixed 2.32 V reset threshold is required for single-supply monitoring. The low 24 µA quiescent current makes it appropriate for energy-constrained designs. The inclusion of a watchdog timer simplifies firmware complexity for fault recovery. The SC-70-5 package is ideal for space-sensitive layouts. Consider the 2.5% accuracy tolerance for precise voltage detection requirements.

Supervisors Part Context

The ADM823 series comprises voltage supervisors designed for monitoring power rails in digital systems. This specific model integrates watchdog capabilities, distinguishing it from basic reset controllers. It belongs to the broader portfolio of power management ICs from Analog Devices, targeting reliable system startup and fault protection in embedded environments.

Supervisors Replacement Considerations

ADM823TYKSZ-R7: Features a different threshold voltage (3.08 V) but shares similar package and functionality.
