ADM1813-5AKS-REEL

Supervisors Overview

The ADM1813-5AKS-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as a reset generator IC. It operates within a maximum supply voltage of 5.5 V and features a fixed threshold voltage of 5 V for power monitoring. The device provides a push-pull output configuration and includes a manual reset function, allowing for external control over the reset state. It does not incorporate a watchdog timer or battery backup switch capabilities. The reset delay time is specified at 250 ms, ensuring stable signal generation during power transitions. Operating temperatures range from -40°C to +105°C, and it is housed in an SC-70-3 surface-mount package with a quiescent current of 16 µA.

Supervisors Feature Summary

• Includes a manual reset input pin for external control of the reset signal state
• Features a push-pull output stage capable of sourcing and sinking current without requiring external pull-up resistors
• Provides a fixed 5 V threshold voltage for precise monitoring of 5 V power rails
• Operates across an extended industrial temperature range suitable for harsh environments

Supervisors Applications

• Microprocessor system reset generation for 5 V logic families
• Power supply supervision in industrial control equipment
• Reset circuitry for embedded systems requiring manual intervention capability
• Battery-powered devices where low quiescent current is critical

Supervisors Procurement Notes

Verify the specific suffix 'KS' against official Analog Devices documentation to confirm package type and temperature grade accuracy. Confirm RoHS compliance status through the manufacturer's latest datasheet, as historical records may vary. Ensure the reel packaging matches your automated assembly requirements. Cross-reference the part number with current lifecycle status to avoid obsolescence risks during production planning.

Supervisors Selection Notes

Select this component when a fixed 5 V threshold is required alongside manual reset functionality. The push-pull output simplifies board layout compared to open-drain alternatives. Consider the SC-70-3 package size constraints and thermal performance within the -40°C to +105°C operating range. Verify that the 250 ms reset delay aligns with your system's power-up timing requirements.

Supervisors Part Context

This part belongs to the ADM1813 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and package options. The ADM1813 variant specifically distinguishes itself by including a manual reset feature, unlike the ADM1811 which lacks this function. It serves as a dedicated power management solution for ensuring reliable system initialization.

Supervisors Replacement Considerations

The ADM1811-5ARTZ-REEL is a related component but lacks the manual reset feature. Verify if the absence of manual reset is acceptable for your design. No direct public substitute part numbers are confirmed in the provided data.
