ADM1815-5AKS-RL7

Supervisors Overview

The ADM1815-5AKS-RL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.0 V to 5.5 V and features a fixed threshold voltage of 5.0 V. The device provides a reset signal with a typical delay time of 250 ms. It utilizes an SC-70-3 (KS-3) surface-mount package and supports push-pull output configuration. The component functions without manual reset, watchdog timer, or battery backup switch capabilities.

Supervisors Feature Summary

• Provides reliable power-supply monitoring for microprocessor systems
• Generates active-low reset signals upon power-up or brown-out events
• Ensures stable operation through defined reset pulse width and delay

Supervisors Applications

• Microprocessor power supply supervision
• Embedded system reset generation
• Portable electronic device power management

Supervisors Procurement Notes

Verify current availability status as distribution channels may indicate limited stock or discontinuation. Confirm RoHS compliance details and specific ordering suffixes match design requirements. Cross-reference datasheet revisions to ensure parameter consistency before final procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 5.0 V threshold is required for single-input voltage monitoring. The SC-70-3 package suits space-constrained designs. Ensure the application does not require manual reset inputs or watchdog functionality, as these are absent in this specific variant.

Supervisors Part Context

This part belongs to the ADM181x series of microprocessor reset circuits from Analog Devices. The series offers various threshold voltages and package options. The ADM1815 specifically denotes the 5.0 V threshold variant within this family of supervisory devices.

Supervisors Replacement Considerations

Check for ADM1815-5AKSZ-RL7 as a potential alternative with similar specifications. Verify pin compatibility and electrical parameters against original design constraints before substitution.
