The DRV5011 device is a digital-latch Hall effect sensor designed for motors and other rotary systems.
With an efficient low-voltage architecture that operates from 2.5 V to 5.5 V, the device is offered in a standard SOT-23 package, and a 0.4-mm thin X2SON that is 90% smaller. The output is a push-pull driver that requires no pullup resistor, enabling more compact systems. ™
When a south magnetic pole is near the top of the package and the BOP threshold is exceeded, the device drives a low voltage. The output stays low until a north pole is applied and the BRP threshold is crossed, which causes the output to drive a high voltage. Alternating north and south poles are required to toggle the output, and integrated hysteresis separates BOP and BRP to provide robust switching.
The device produces consistent performance across a wide ambient temperature range of –40°C to +135°C.
