MCQ1823GQTE-550BRNAEC-Z

Current Sensors Overview

The MCQ1823GQTE-550BRNAEC-Z is an automotive-grade linear Hall-effect current sensor IC from Monolithic Power Systems. It features a ±50A bidirectional current range with ±2.5% total accuracy over temperature. The device operates on a single 3.3V or 5V supply and includes integrated overcurrent detection (OCD) with a 1μs response time. It utilizes a differential Hall array to reject external gradient magnetic fields and employs a low-resistance 0.6mΩ internal conductor. The component is housed in a compact 12-TQFN (3x3mm) package and holds AEC-Q100 Grade 1 certification for -40°C to +125°C operation.

Current Sensors Feature Summary

• Integrated fast overcurrent detection (OCD) function for monitoring system OC events
• Differential Hall array design eliminates interference from uniform or gradient stray magnetic fields
• Low resistance internal primary conductor allows high current flow near the sensor
• Rotating current technology ensures stable low offset performance

Current Sensors Applications

• Automotive battery management systems
• Electric vehicle motor control drives
• On-board charger (OBC) current monitoring
• DC-DC converter output sensing

Current Sensors Procurement Notes

Verify the specific suffix codes against official Monolithic Power Systems documentation to ensure correct configuration. Confirm that the ordering suffix aligns with the required packaging format and calibration specifications. Cross-reference the part number with the manufacturer's active product list to validate lifecycle status. Ensure compatibility with the target application's voltage levels and thermal requirements before finalizing procurement orders.

Current Sensors Selection Notes

Select this component when space-constrained automotive designs require precise AC or DC current sampling. The ±50A range suits applications needing robust overload protection via the integrated OCD feature. Consider the 120kHz bandwidth for high-frequency switching environments. The TQFN-12 package facilitates PCB area reduction compared to larger alternatives while maintaining necessary isolation and accuracy standards.
