TMCS1107A3BQDR

Current Sensors Overview

The TMCS1107A3BQDR is an automotive-grade, galvanically isolated Hall-effect current sensor manufactured by Texas Instruments. It features ±420V basic isolation and supports AC/DC current measurement with a bandwidth of 80kHz. The device operates on a supply voltage of 3V to 5.5V and provides an analog output. It is housed in an 8-pin SOIC package and meets AEC-Q100 qualification standards for operation between -40°C and +125°C.

Current Sensors Feature Summary

• Galvanically isolated Hall-effect sensing technology for high-voltage applications
• Automotive qualification compliant with AEC-Q100 standards
• Bidirectional current measurement capability with high linearity accuracy

Current Sensors Applications

• Electric vehicle battery management systems
• Motor control drives
• Industrial power supply monitoring

Current Sensors Procurement Notes

Verify the specific suffix BQDR matches the required tape-and-reel packaging configuration. Confirm that the ±420V isolation rating aligns with system safety requirements. Ensure the SOIC-8 footprint compatibility with PCB layout constraints before finalizing procurement orders.

Current Sensors Selection Notes

Select this component when bidirectional AC or DC current sensing is required in automotive environments. The 80kHz bandwidth suits most motor drive and power conversion frequencies. Consider the ±0.5% linearity specification for precision applications requiring accurate signal fidelity without external calibration.

Current Sensors Part Context

This part belongs to the TMCS1100 series of board-mount current sensors. It shares the same Hall-effect sensing architecture as other family members but offers specific isolation and bandwidth characteristics tailored for automotive grade reliability and performance under harsh thermal conditions.

Current Sensors Replacement Considerations

The TMCS1100A3QDRQ1 is a related variant within the same product family. Verify if the different current rating or isolation specifications of the TMCS1100 series meet the design requirements before substituting.
