Product Overview
The DRV5055 is a Texas Instruments ratiometric linear Hall-effect magnetic sensor for proportional magnetic flux density sensing. Its analog output is ratiometric and uses a VCC/2 quiescent offset, with specified quiescent output values of 2.5 V typical at 5 V supply and 1.65 V typical at 3.3 V supply when B = 0 mT and TA = 25 °C.
The device operates from supported 3.3 V and 5 V supplies, with recommended supply voltage ranges of 3.0 V to 3.63 V and 4.5 V to 5.5 V. Electrical parameters include 20 kHz sensing bandwidth, 10 µs propagation delay from magnetic field change to OUT change, and operating supply current of 3 mA typical at 5 V or 2 mA typical at 3.3 V when B = 0 mT.
Package options include DBZ SOT-23, 3 measuring 2.92 mm x 2.37 mm and LPG TO-92, 3 measuring 4 mm x 1.52 mm. Pin functions are VCC, OUT, and GND, with a recommended ceramic capacitor to ground of at least 0.01 µF on VCC. The DRV5055 is suited to magnetic flux density measurement, analog magnetic field monitoring, and sensor designs using its specified sensitivity, range, and temperature compensation options.
