ADM1815-10AKS-RL7

Supervisors Overview

The ADM1815-10AKS-RL7 is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor voltage levels and generate reset signals. It operates within a supply voltage range of 2.9V to 5.5V with a fixed threshold of 4.40V. The device features a push-pull output and supports manual reset functionality. It is housed in an SC-70-3 surface-mount package and functions reliably across an industrial temperature range of -40°C to +105°C.

Supervisors Feature Summary

• Monitors single power supply rail for under-voltage conditions
• Provides active-low reset signal via push-pull output
• Supports manual reset input for system control
• Operates at low quiescent current for energy efficiency

Supervisors Applications

• Portable battery-powered equipment requiring voltage supervision
• Microcontroller and DSP power-on reset circuits
• Industrial control systems with wide temperature requirements
• Communication infrastructure power management

Supervisors Procurement Notes

Verify the specific suffix RL7 indicates tape and reel packaging when sourcing. Confirm the AKS variant matches the required SC-70-3 package and temperature grade. Check current lifecycle status as older revisions may be discontinued or subject to limited availability from distributors.

Supervisors Selection Notes

Select this component when a fixed 4.40V threshold is appropriate for the target logic level. Ensure the SC-70-3 package fits the PCB layout constraints. Compare against ADM1815 variants with different thresholds if the system voltage differs. Verify manual reset pin compatibility with the microcontroller GPIO configuration.

Supervisors Part Context

Part of the ADM181x series of simple reset supervisors from Analog Devices. This family provides reliable power monitoring for embedded systems. The ADM1815 specifically targets applications needing a fixed threshold without external resistor dividers, simplifying design compared to programmable alternatives.

Supervisors Replacement Considerations

ADM1815-10AKSZ-R7 is a parameter-equivalent alternative available in cut-tape packaging. Other ADM1815 variants with different voltage thresholds (e.g., 2.63V, 3.08V) are functionally similar but require threshold verification.
