3 Description

The DRV5053 device is a chopper-stabilized Hall IC

that offers a magnetic sensing solution with superior

sensitivity stability over temperature and integrated

protection features.

The 0-V to 2-V analog output responds linearly to the

applied magnetic flux density, and distinguishes the

polarity of magnetic field direction. A wide operating

voltage range from 2.5 V to 38 V with reverse polarity

protection up to –22 V makes the device suitable for a

wide range of industrial and consumer applications.

Internal protection functions are provided for reverse

supply conditions, load dump, and output short circuit

or overcurrent.
