ADM1818-5AKS-REEL7

Supervisors Overview

The ADM1818-5AKS-REEL7 is a microprocessor reset circuit manufactured by Analog Devices Inc. It functions as a voltage supervisor with an open-drain or open-collector output, providing a low-active reset signal. The device monitors a single voltage channel with a typical threshold of 4.62 V. It features a minimum reset timeout of 100 ms and operates within a temperature range of -40°C to 105°C. The component is housed in a SC-70-3 surface-mount package.

Supervisors Feature Summary

• Provides reliable power supply monitoring for microprocessor systems
• Generates reset signals upon detection of under-voltage conditions
• Features open-drain output compatible with various logic families

Supervisors Applications

• Microprocessor system supervision
• Portable equipment power management
• Battery-powered device reset generation

Supervisors Procurement Notes

Verify the specific suffix '5A' indicates the 4.62 V threshold variant. Confirm package integrity for SC-70-3. Check for obsolescence status as related variants may be discontinued. Ensure compatibility with target voltage levels before integration.

Supervisors Selection Notes

Select this component when a fixed 4.62 V threshold is required for system supervision. Consider the SC-70-3 package size constraints. Verify that the open-drain output configuration meets the pull-up requirements of the connected microprocessor reset pin.

Supervisors Part Context

This part belongs to the ADM1818 series of simple reset circuits designed for cost-sensitive applications. It is often used alongside other ADM18xx variants offering different voltage thresholds. The series supports standard voltage rails like 5V and 3.3V systems.

Supervisors Replacement Considerations

ADM1818-R23AKSZ-R7 is listed as a parameter equivalent substitute.
