ADM12914-1ARQZ-RL7

Supervisors Overview

The ADM12914-1ARQZ-RL7 is a quad undervoltage/overvoltage (UV/OV) positive/negative voltage supervisor manufactured by Analog Devices Inc. It features adjustable UV and OV input thresholds with industry-leading threshold accuracy of ±0.8% over the extended temperature range. The device provides a 1 V buffered reference output and open-drain UV and OV reset outputs. Reset timeout is adjustable with a disable option, and outputs are guaranteed down to VCC of 1 V. Supply current is 62 μA. It operates from -40°C to +125°C in a 16-lead QSOP package.

Supervisors Feature Summary

• Quad supervision for up to two negative rails
• Adjustable UV and OV input thresholds
• Open-drain UV and OV reset outputs

Supervisors Applications

• Monitoring negative voltage rails
• System reliability enhancement
• Voltage level specification compliance

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm packaging configuration. Ensure compatibility with required operating temperatures and voltage ranges before integration. Cross-reference part numbers with manufacturer databases to avoid substitution errors.

Supervisors Selection Notes

Select this component when precise monitoring of multiple negative voltage rails is required. Consider the ±0.8% accuracy for critical applications. Evaluate the need for adjustable thresholds and reset timeouts relative to system design constraints.

Supervisors Part Context

Part of Analog Devices' supervisory IC portfolio designed to improve system reliability by ensuring voltage levels remain within specified limits. Complements other supervisors like ADM2914 and ADM6339 for comprehensive power management solutions.

Supervisors Replacement Considerations

Consult official documentation for confirmed substitute part numbers. Verify functional equivalence regarding threshold accuracy, supply current, and package dimensions before implementation.
