Overview
The DRV5053EAQDBZR, produced by Texas Instruments, is a chopper-stabilized Hall IC that provides a magnetic sensing solution with superior sensitivity stability over temperature and integrated protection features. This analog-bipolar Hall Effect sensor offers a linear output that responds to the applied magnetic flux density and distinguishes the polarity of the magnetic field direction. With a wide operating voltage range from 2.5 V to 38 V and reverse polarity protection up to –22 V, it is suitable for a variety of industrial and consumer applications.
