Product Overview
The DRV5056 is a Texas Instruments unipolar linear Hall-effect magnetic sensor. It produces an output proportional to magnetic flux density from a magnetic south pole, with a typical 0.6 V quiescent output at B = 0 mT and a linear output range from VQ to VCC - 0.2 V.
The device supports 3.3 V and 5 V supply systems through recommended VCC ranges of 3 V to 3.6 V and 4.5 V to 5.5 V. Electrical characteristics include 6 mA typical operating supply current, 20 kHz typical sensing bandwidth, 150 µs typical power-on time, and 10 µs typical propagation delay from a magnetic field change to OUT.
Package options include the DBZ 3-pin SOT-23 and LPG 3-pin TO-92. Pin functions differ by package: SOT-23 uses pin 1 VCC, pin 2 OUT, and pin 3 GND, while TO-92 uses pin 1 VCC, pin 2 GND, and pin 3 OUT. The VCC pin recommendation is at least a 0.1 µF ceramic bypass capacitor to ground.
