ADM1818-10AKS-RL7

Supervisors Overview

The ADM1818-10AKS-RL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply voltages and generate reset signals. It operates within a supply voltage range up to 5.5 V and features a typical reset threshold of 2.88 V. The device provides a manual reset input for system control and includes a fixed reset delay time of 100 ms to ensure stable operation during power transitions. It draws a low operating current of 16 µA, making it suitable for battery-powered applications. The component is housed in an SC-70-3 surface-mount package and supports an industrial temperature range from -40°C to +105°C.

Supervisors Feature Summary

• Provides reliable voltage monitoring with a dedicated reset output for system protection
• Includes a manual reset input allowing external control over the reset state
• Features a fixed reset delay timer to prevent premature resets during power-up
• Operates with low quiescent current to support energy-efficient designs

Supervisors Applications

• Monitoring 2.5 V, 3 V, 3.3 V, and 5 V power rails in embedded systems
• Microcontroller and digital logic power supply supervision
• Battery-operated devices requiring low standby current
• Industrial control systems needing wide temperature range operation

Supervisors Procurement Notes

Verify availability status as this part may be discontinued or subject to limited supply. Confirm that the SC-70-3 package matches your PCB footprint requirements. Ensure the 2.88 V threshold aligns with your specific voltage rail monitoring needs. Check for RoHS compliance documentation if required for your manufacturing process. Validate lead times through authorized distributors due to potential obsolescence.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisor with manual reset capability is required. The fixed 100 ms delay suits applications where immediate reset upon brownout is not critical. Consider the 16 µA current consumption for battery life calculations. Verify that the SC-70-3 package size fits your space constraints. Compare against alternatives if adjustable thresholds or watchdog timers are needed.

Supervisors Part Context

The ADM1818 belongs to Analog Devices' ADM181x series of voltage supervisors. This family offers various threshold options and packages to suit different monitoring requirements. The ADM1818 specifically targets applications needing a basic reset function with manual override. It complements other PMIC components in power management architectures.

Supervisors Replacement Considerations

The ADM1818-R23AKSZ-R7 is listed as a parameter-equivalent replacement. Verify pin compatibility and threshold voltage differences before substitution. Other ADM181x variants may offer similar functionality but differ in package or threshold settings.
