ADM1812-5AKSZ-RL7

Supervisors Overview

The ADM1812-5AKSZ-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 4.62 V for power monitoring. The device provides a reset output with a typical delay time of 150 ms to ensure stable power-up conditions. It is housed in a compact SC-70-3 surface-mount package, suitable for space-constrained designs. The component supports active high or active low push-pull outputs and lacks manual reset or watchdog timer functionalities.

Supervisors Feature Summary

• Provides reliable system reset generation upon detection of undervoltage conditions
• Ensures processor stability through a defined reset delay period during power transitions
• Offers flexible output polarity configuration to match specific logic requirements

Supervisors Applications

• Microprocessor power supply supervision
• Battery-powered electronic systems
• Embedded controller reset circuits

Supervisors Procurement Notes

Verify the exact suffix AKSZ against the manufacturer datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status as indicated in the official documentation. Check current availability status directly with authorized distributors as supply levels may vary. Ensure the ordering part number matches the required threshold voltage and output configuration.

Supervisors Selection Notes

Select this component when a fixed 4.62 V threshold is required for 5 V logic systems. Consider the SC-70-3 package size for limited board area applications. Verify that the 150 ms reset delay meets the timing requirements of the target microprocessor. Ensure the operating temperature range aligns with the intended environmental conditions.

Supervisors Part Context

This part belongs to the ADM181x series of supervisory circuits from Analog Devices. These devices are designed to monitor voltage levels and generate reset signals for digital systems. The series typically includes variants with different thresholds and packages to support various standard voltage rails in consumer and industrial electronics.

Supervisors Replacement Considerations

Check the ADM1812-5ARTZ-RL7 for alternative packaging options such as SOT-23-3. Verify functional compatibility with other ADM1812 variants offering similar threshold voltages.
