High current sensing Hall sensor

TMCS1100A3QDR General Description

Featuring four sensitivity options, the TMCS1100 operates efficiently on a single 3V to 5.5V power supply, eliminating ratiometry errors and enhancing supply noise rejection. The sensor's output voltage is directly proportional to the input current, with positive current considered when flowing into the positive input pin. The VREF input pin enables adjustment of the zero-current output voltage, facilitating bidirectional or unidirectional current sensing. With a maximum supply current of 6 mA, the TMCS1100A3QDR is a versatile and efficient solution for current measurement applications
