ADM1812-5AKS-RL7

Supervisors Overview

The ADM1812-5AKS-RL7 is a microprocessor reset circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.62 V for power monitoring. The device provides a push-pull output type and includes a manual reset input capability. It incorporates a reset delay time of 250 ms to ensure stable power-up sequencing. The component is housed in an SC-70-3 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Supervisors Feature Summary

• Integrates a manual reset input for user-initiated system control alongside automatic power-on reset functionality.
• Provides a push-pull output stage capable of driving load currents directly without external pull-up resistors.
• Features a fixed threshold voltage setting optimized for standard 5 V logic systems.

Supervisors Applications

• Microprocessor power supply supervision
• Embedded system reset generation
• Industrial control unit power monitoring

Supervisors Procurement Notes

Verify the specific suffix 'RL7' indicates reel packaging configuration against official Analog Devices documentation. Confirm RoHS compliance status and lead-free pin availability through current datasheets. Check for obsolescence notices or lifecycle changes prior to final procurement decisions.

Supervisors Selection Notes

Select this component when a fixed 4.62 V threshold is required for 5 V systems. Ensure compatibility with SC-70-3 footprint constraints. Verify that the push-pull output drive strength meets the target load requirements without additional buffering.

Supervisors Part Context

This part belongs to the ADM181x series of supervisory circuits designed for reliable microprocessor reset generation. It complements other variants like the ADM1813 and ADM1818, which offer different thresholds or output configurations while maintaining similar package and operational characteristics.

Supervisors Replacement Considerations

ADM1812-5ARTZ-RL7 serves as a parameter-equivalent alternative with identical electrical specifications but utilizes an SOT-23-3 package instead of SC-70-3. Verify mechanical fit before substitution.
