Overview
The AMC23C11DWV is a fast-response reinforced isolated comparator in an 8-pin SOIC package. It features a wide high-side supply range of 3V to 27V and a low-side range of 2.7V to 5.5V. The device provides adjustable trip thresholds from 20mV to 2.7V via the REF pin, with a typical propagation delay of 240ns. It offers a minimum common-mode transient immunity (CMTI) of 75V/ns and certified reinforced isolation up to 7000VPK and 5000VRMS. The open-drain output supports transparent or latch modes.
Feature Summary
- Reinforced galvanic isolation barrier certified for safety applications
- Adjustable trip threshold using external resistor on reference pin
- Configurable open-drain output with selectable latch mode
Applications
- Overcurrent detection in motor drives
- Overvoltage detection in frequency inverters
- Protection circuits in solar inverters
- Fault detection in DC/DC converters
Procurement Notes
Verify the specific ordering suffix DWV corresponds to the 8-pin wide-body SOIC package. Confirm that the component meets the required safety certifications for your application, specifically DIN EN IEC 60747-17 and UL1577 standards. Ensure design parameters align with the specified extended industrial temperature range of –40°C to +125°C.
Selection Notes
Select this component when high-voltage isolation is required alongside precise threshold detection. The wide high-side supply range accommodates various bus voltages. Consider the latch function if holding fault states is necessary. Verify that the PCB layout maintains the required creepage and clearance distances to preserve the reinforced isolation rating.
Part Context
This part belongs to Texas Instruments' family of isolated comparators designed for robust signal transmission across isolation barriers. Unlike standard amplifiers, it focuses on rapid state changes and configurable thresholds. The DWV suffix denotes the specific surface-mount packaging suitable for automated assembly processes.
Replacement Considerations
No public confirmed substitute part numbers are available.
