AMC23C14DWV

Overview

The AMC23C14DWV is a dual, fast-response, reinforced isolated window comparator housed in an 8-pin SOIC package. It features a high-side supply range of 3V to 27V and a low-side supply range of 2.7V to 5.5V. The device includes one adjustable window comparator (±20mV to ±300mV) and one fixed threshold comparator (±300mV). It supports positive-comparator mode with thresholds up to 2.7V. Key electrical parameters include a typical propagation delay of 280ns, minimum common-mode transient immunity of 15V/ns, and open-drain outputs. It operates over an extended industrial temperature range from –40°C to +125°C.

Feature Summary

• Dual channel architecture providing both adjustable and fixed trip thresholds for versatile monitoring applications.
• Reinforced galvanic isolation barrier certified for safety standards including VDE 0884-17 and UL1577.
• High common-mode transient immunity ensures reliable operation in electrically noisy environments.
• Supports positive-comparator mode for unidirectional voltage monitoring via the REF pin.

Applications

• Overcurrent or overvoltage detection in motor drives
• Protection circuits in frequency inverters
• Fault detection in solar inverters
• Monitoring in DC/DC converters

Procurement Notes

Verify the specific ordering suffix matches the required packaging format, as standard production data may vary by distributor. Confirm that the component meets the necessary safety certifications for your specific application environment. Ensure the design adheres to the recommended operating conditions regarding supply voltages and thermal limits to maintain device reliability and insulation integrity.

Selection Notes

Select this component when dual-channel comparison with distinct threshold requirements is necessary within an isolated system. The adjustable threshold capability allows customization for sensitive detection, while the fixed comparator provides a constant reference. Consider the wide high-side supply range if interfacing with higher voltage domains directly without additional level shifting.

Part Context

This device belongs to the AMC23C14 series of isolated comparators from Texas Instruments. It is designed to replace traditional non-isolated comparison solutions in systems requiring galvanic separation. The part integrates the comparison logic and isolation barrier into a single compact package, simplifying board layout compared to discrete solutions.
