AMC23C10DWVR

Overview

The AMC23C10DWVR is a fast-response, reinforced isolated comparator with dual outputs in an 8-pin SOIC package. It features a high-side supply range of 3V to 27V and a low-side range of 2.7V to 5.5V. The device provides open-drain and push-pull outputs with a typical propagation delay of 230ns and maximum trip threshold error of ±6mV. Common-mode transient immunity reaches 100V/ns for the push-pull output. It supports reinforced isolation up to 7000VPK per VDE standards and 5000VRMS per UL1577, operating from -40°C to +125°C.

Feature Summary

• Provides galvanic isolation between high-voltage analog inputs and low-voltage digital circuitry using a reinforced SiO2-based capacitive barrier.
• Features dual digital outputs consisting of an open-drain buffer and a push-pull buffer for flexible interface compatibility.
• Includes an integrated low-dropout regulator enabling direct operation from wide-range high-side power supplies without external components.
• Delivers high common-mode transient immunity and magnetic field resistance suitable for noisy industrial environments.

Applications

• Zero-crossing detection in solid-state relays and circuit breakers
• General-purpose monitoring in hybrid, electric, and powertrain systems
• Battery management systems and onboard chargers
• Factory automation and building control systems

Procurement Notes

Verify that the specific ordering suffix matches the required package variant and tape-and-reel configuration. Confirm compliance with relevant safety certifications such as VDE 0884-17 or UL1577 if the application requires certified isolation barriers. Ensure the design accounts for the extended industrial temperature range specifications during procurement planning.

Selection Notes

Select this component when high-speed response and reinforced isolation are required for zero-crossing detection. The dual output options allow designers to choose between open-drain flexibility and push-pull drive strength based on system load requirements. Consider the wide input voltage range and built-in hysteresis for robust signal comparison in high-noise environments.

Part Context

This device belongs to the AMC23C10 family of isolated comparators designed for high-voltage sensing applications. It utilizes Texas Instruments' capacitive isolation technology to provide safety-certified galvanic separation. The part is distinct from isolation amplifiers by offering direct digital switching rather than analog signal conditioning.

Replacement Considerations

AMC23C10Q1: Automotive-grade version with similar electrical characteristics but qualified for automotive reliability standards.
