TMCS1101A1BQDR General Description

The output voltage of the TMCS1101 is directly proportional to the input current, offering four sensitivity options to cater to different application requirements. The fixed sensitivity eliminates ratiometry errors, allowing the sensor to operate seamlessly with a single 3-V to 5.5-V power supply. With positive current flow considered as the default polarity, both unidirectional and bidirectional sensing variants are available to suit various usage scenarios

Key Features

Prioritize data integrity
