1. Describe

The DRV5053EAQDBZR device is a chopper-stabilized Hall IC that provides a magnetic sensing solution with excellent sensitivity stability and integrated protection over temperature. The 0 to 2V analog output responds linearly to the applied magnetic flux density and distinguishes the polarity of the magnetic field direction. The wide operating voltage range of 2.5 to 38 V and reverse polarity protection up to –22 V make the device suitable for a variety of industrial and consumer applications. Internal Protection for Reverse Supply Conditions, Load Dump and Output Short Circuit or overcurrent.
