ADM1815-R23AKSZ-RL

Supervisors Overview

The ADM1815-R23AKSZ-RL is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor system voltage levels. It operates within a supply voltage range of 4V to 5.5V and features a fixed threshold voltage of 2.31V for reset generation. The device provides a push-pull output type and supports manual reset functionality without an integrated watchdog timer or battery backup switch. It is housed in a compact SC-70-3 surface-mount package, suitable for space-constrained applications requiring reliable power management supervision.

Supervisors Feature Summary

• Monitors system voltage with a fixed 2.31V threshold for accurate reset generation
• Features push-pull output configuration for robust signal driving capabilities
• Supports manual reset input for user-initiated system control
• Operates reliably across extended industrial temperature ranges

Supervisors Applications

• Portable electronic devices requiring low-power supervision
• Battery-operated systems needing voltage monitoring
• Embedded controllers requiring reset signal generation
• Industrial equipment with strict power integrity requirements

Supervisors Procurement Notes

Verify the specific suffix 'R23' confirms the 2.31V threshold variant during procurement. Confirm the 'KSZ' package designation matches the required SC-70-3 footprint. Ensure compatibility with existing board layouts regarding pin assignments. Check for RoHS compliance status if environmental regulations apply. Validate that the push-pull output aligns with downstream logic requirements.

Supervisors Selection Notes

Select this component when a fixed 2.31V threshold is necessary for precise voltage monitoring. Consider the SC-70-3 package size for tight spatial constraints. Evaluate the push-pull output against open-drain alternatives based on load requirements. Verify that the absence of a watchdog timer meets system safety needs. Compare operating current consumption against other supervisory ICs for efficiency optimization.

Supervisors Part Context

This part belongs to the ADM1815 series of supervisory circuits from Analog Devices. It is functionally related to the ADM1810-13 and ADM1815-18 series documents referenced in manufacturer literature. The device serves as a dedicated voltage supervisor within the broader PMIC portfolio, focusing on simple reset and power-on-reset functions for microprocessor systems.

Supervisors Replacement Considerations

The ADM1818-R23AKSZ-R7 is listed as a parameter equivalent substitute. Verify pinout compatibility and threshold voltage matching before substitution. Confirm package dimensions align with existing PCB footprints. Assess thermal performance differences between the original and replacement parts.
