DRV5011 - Texas Instruments

DRV5011 Digital-Latch Hall Effect Sensor

The DRV5011 device is a digital-latch Hall effect sensor designed for motors and other rotary systems. The device has an efficient low-voltage architecture that operates from 2.5 V to 5.5 V. The device is offered in standard SOT-23, and low-profile X2SON and DSBGA packages. The output is a push-pull driver that requires no pullup resistor, enabling more comp.
