DRV5055

Texas Instruments · Hall-effect sensor · SOT-23

Outputs an analog voltage proportional to the magnetic field through its face, centered at half the supply so it reads both magnetic poles. It is ratiometric to VCC, so an ADC on the same rail measures field directly, and on-chip temperature compensation holds the sensitivity flat over temperature, which older linear Hall sensors struggle with. Sensitivity options (A1-A4) trade range against resolution. Runs from 3.3 or 5 V. A precise analog sensor for position, angle, and current sensing with a magnet.

Pinout

Pin Name Type Function
1 VCC power_in Power supply, 3.0 to 3.63 V or 4.5 to 5.5 V. TI recommends connecting this pin to ground via a ceramic bypass capacitor of at least 0.01 µF. Absolute-maximum V_CC is 7 V.
2 OUT output Analog output; ratiometric to V_CC with a V_CC/2 quiescent offset. Output-drive current range is -1 to +1 mA and the linear output range is 0.2 V to V_CC - 0.2 V.
3 GND power_in Ground reference for the device.
