ADM1815-R23AKSZ-R7

Supervisors Overview

The ADM1815-R23AKSZ-R7 is a voltage 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 2.31 V. The device provides a push-pull output with an active-low reset signal. It includes a manual reset input capability and offers a reset delay time of 250 ms. The component is housed in a compact SC-70-3 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Supervisors Feature Summary

• Provides precise power supply monitoring with a fixed threshold for reliable system supervision
• Features a manual reset input allowing external control over the reset state
• Delivers a push-pull active-low reset output for direct interface with digital logic

Supervisors Applications

• Microprocessor and microcontroller power supply supervision
• Battery-powered equipment voltage monitoring
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the 2.31 V threshold variant matches design requirements. Check current availability status as distribution may vary. Ensure the SC-70-3 package fits the PCB layout constraints. Validate RoHS compliance documentation for regulatory adherence.

Supervisors Selection Notes

Select this component when a fixed 2.31 V threshold is required for low-voltage systems. The manual reset feature is suitable for applications needing external intervention. The wide operating temperature range supports industrial environments. Consider the push-pull output for driving loads directly without additional pull-up resistors.

Supervisors Part Context

This part belongs to the ADM1815 series of supervisory circuits designed for single-input voltage monitoring. It complements other variants in the family that offer different threshold voltages. The series is intended for cost-sensitive applications requiring basic reset generation without watchdog timers.

Supervisors Replacement Considerations

ADM1815-R23AKSZ-R7 is the primary equivalent. Verify pinout compatibility with existing designs. Check if alternative thresholds are acceptable if exact matching is not possible.
