AMC23C12QDWVRQ1

Overview

The AMC23C12QDWVRQ1 is an automotive-grade, fast-response, reinforced isolated window comparator with adjustable threshold and latch function. It features a wide high-side supply range of 3V to 25V and a low-side supply range of 2.7V to 5.5V. The device provides a trip threshold error of ±1% (max) at 250mV and supports propagation delay of 280ns typical. It offers high common-mode transient immunity of 55V/ns minimum and certified reinforced isolation up to 7000VPK per DIN EN IEC 60747-17.

Feature Summary

• Reinforced galvanic isolation barrier certified for safety standards including VDE 0884-17 and UL1577.
• Adjustable trip threshold via external resistor or reference voltage in window or positive-comparator modes.
• Open-drain output with selectable transparent or latch mode controlled by digital input.
• High common-mode transient immunity resistant to magnetic interference.

Applications

• Overcurrent or overvoltage detection in HEV/EV charging piles
• HEV/EV onboard chargers (OBC)
• HEV/EV DC/DC converters
• HEV/EV traction inverters

Procurement Notes

Verify the specific ordering suffix Q1 confirms AEC-Q100 qualification for automotive use. Confirm the DWVR package variant matches the required SOIC-8 width and reel specifications. Ensure design compliance with the specified safety limiting values and thermal derating curves to maintain isolation integrity under fault conditions.

Selection Notes

Select this component when high-side voltages exceed standard logic levels and precise analog threshold monitoring is required. The wide input range and adjustable hysteresis make it suitable for shunt-based current sensing or direct voltage monitoring in noisy environments requiring robust signal isolation.

Part Context

This part belongs to the AMC23C12-Q1 family of isolated comparators designed for harsh automotive electrical environments. It integrates a high-voltage tolerant analog front end with a digital isolator, providing a complete solution for fault detection without external isolation components.
