ADM1815-20AKSZ-RL

Supervisors Overview

The ADM1815-20AKSZ-RL is a single-channel voltage supervisor manufactured by Analog Devices Inc. It operates within an extended temperature range of -40°C to +105°C and utilizes a surface-mount SC70-3 package measuring 2.00 x 1.25mm. The device provides a push-pull, active-low reset output with a fixed threshold level of 4.62V. Designed for monitoring standard supply voltages such as 2.5V, 3V, 3.3V, and 5V, it ensures reliable system reset generation without requiring manual intervention or external components.

Supervisors Feature Summary

• Provides reliable low-cost voltage monitoring with integrated reset output generation
• Suitable for monitoring multiple standard power supply voltage levels including 2.5V, 3V, 3.3V, and 5V
• Features a compact SC70-3 surface mount package for space-constrained designs

Supervisors Applications

• Microprocessor reset circuits
• Power supply supervision in embedded systems
• Battery-powered device protection

Supervisors Procurement Notes

Verify the specific suffix '20' indicates the 4.62V threshold variant when sourcing. Confirm the 'KSZ' designation corresponds to the SC70-3 package and reel packaging format. Ensure compatibility with the target operating temperature range of -40°C to +105°C for industrial applications. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.

Supervisors Selection Notes

Select this component when a simple, cost-effective solution for single-supervision is required. It is appropriate for designs needing a fixed 4.62V threshold rather than adjustable options. Consider the SC70-3 package size constraints against available board space. Verify that the push-pull output drive capability meets the input requirements of the downstream logic or microcontroller reset pin.

Supervisors Part Context

This part belongs to the ADM1815 series of supervisory circuits from Analog Devices. The series includes variants with different threshold voltages and package types, such as the ARTZ and AKSZ suffixes. These devices are designed to replace discrete resistor networks and comparators, simplifying circuit design while maintaining high reliability for critical reset functions in digital systems.

Supervisors Replacement Considerations

Direct substitutes include other ADM1815 variants with matching thresholds, such as ADM1815-20ARTZ-RL7. Verify package compatibility between SC70-3 and alternative footprints like SOT-23-3 before substitution.
