DRV5011 Low-Voltage (Up to 5.5 V) Digital-Latch Hall Effect Sensor

Texas Instruments' DRV5011 digital-latch Hall effect sensors are designed for motors and other rotary systems. The devices have an efficient low-voltage architecture that operates from 2.5 V to 5.5 V. These sensors are offered in the standard SOT-23, low-profile X2SON, and DSBGA packages. 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 B_OP threshold is exceeded, the device drives a low voltage. The output stays low until a north pole is applied and the B_RP threshold is crossed, causing the output to drive a high voltage. Alternating north and south poles are required to toggle the output, and integrated hysteresis separates B_OP and B_RP to provide robust switching. The device produces consistent performance across a wide ambient temperature range of -40°C to +135°C.
