TMCS1108A1UQDRQ1 General Description

Featuring multiple sensitivity options, the TMCS1108-Q1 operates efficiently on a single 3-V to 5.5-V power supply, enhancing noise rejection and eliminating ratiometry errors. Positive current polarity is determined by the direction of flow into the positive input pin, offering flexibility for different sensing needs. Additionally, the sensor's inherent galvanic insulation provides 100-V functional isolation for added safety in circuitry
