ADM1815-R22AKS-RL7

Supervisors Overview

The ADM1815-R22AKS-RL7 is a microprocessor reset circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed reset threshold of 2.18 V. The device provides a push-pull output with a manual reset capability and includes a reset delay time of 250 ms. It functions in an operating temperature range from -40°C to +105°C. The component is housed in a SC-70-3 surface-mount package and is supplied in reel, cut tape, or MouseReel formats.

Supervisors Feature Summary

• Provides reliable low-cost voltage monitoring for standard power supply voltages
• Includes manual reset functionality for system control
• Features a push-pull output stage for direct interface compatibility

Supervisors Applications

• Monitoring 2.5 V, 3 V, 3.3 V, and 5 V power supply rails
• Microprocessor reset generation in embedded systems
• Voltage supervision in portable electronic devices

Supervisors Procurement Notes

Verify current availability status as the part may be discontinued or subject to limited supply. Confirm RoHS compliance requirements against specific project standards, as historical data indicates non-compliance for some variants. Ensure the SC-70-3 package footprint matches the design layout. Validate that the 2.18 V threshold aligns with the target supply voltage monitoring needs.

Supervisors Selection Notes

Select this component when a fixed 2.18 V threshold is required for supervising lower-voltage logic supplies. Consider the 250 ms reset delay for timing-sensitive applications. The SC-70-3 package offers space efficiency for compact designs. Verify that the push-pull output drive strength meets the load requirements of the connected microprocessor reset pin.

Supervisors Part Context

This part belongs to the ADM1813/ADM1815 series of supervisory circuits designed for simple voltage monitoring tasks. These components are intended for applications requiring basic power-on reset and manual reset functions without complex watchdog or battery backup features. The series supports multiple threshold options to accommodate various standard voltage levels.

Supervisors Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include the ADM1818-R23AKSZ-R7. Verify electrical compatibility, specifically the reset threshold and output type, before substitution.
