ADM1815-20AKSZ-RL7

Supervisors Overview

The ADM1815-20AKSZ-RL7 is a single-channel voltage supervisor from Analog Devices, designed to monitor system power rails and generate a reset signal when voltages fall below specified thresholds. It operates within an ambient temperature range of -40°C to +105°C and utilizes a SC70-3 surface-mount package measuring 2.00 x 1.25mm. The device features a fixed reset threshold of 2.55V with a minimum reset timeout of 100ms. It provides an active-low push-pull output suitable for direct interfacing with digital logic circuits.

Supervisors Feature Summary

• Provides simple reset or power-on reset functionality for electronic systems requiring voltage monitoring
• Features an active-low output signal compatible with standard digital logic interfaces
• Ensures reliable operation across extended industrial temperature ranges

Supervisors Applications

• Embedded systems requiring power supply supervision
• Microcontroller reset circuitry in industrial environments
• Portable equipment power management

Supervisors Procurement Notes

Verify the specific suffix (KSZ) against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure the operating environment remains within the stated -40°C to +105°C range. Confirm that the 2.55V threshold aligns with the target system voltage requirements before integration.

Supervisors Selection Notes

Select this component when a fixed 2.55V threshold is appropriate for the monitored rail. The SC70-3 package offers space efficiency for compact designs. Consider the 100ms minimum timeout duration to ensure stable system initialization. Verify compatibility with the downstream logic voltage levels supported by the push-pull output stage.

Supervisors Part Context

This part belongs to the ADM181x series of voltage monitoring circuits manufactured by Analog Devices. These devices are engineered for applications where system reset is critical during brown-out or over-voltage events. The series includes various threshold options and package configurations to suit different design constraints.

Supervisors Replacement Considerations

Check for ADM1815 variants with different threshold voltages or packages if the 2.55V specification does not match the application needs. Verify pinout compatibility when substituting with other single-channel supervisors.
