6.3.2 Magnetic Response

When the DRV5055 is powered, the DRV5055 outputs an analog voltage according to Equation 1:

Equation 1. V O U T = V Q + B × S e n s i t i v i t y ( 25 ° C ) × 1 + S T C × T A - 25 ° C

where

  • VQ is typically half of VCC
  • B is the applied magnetic flux density
  • Sensitivity(25°C) depends on the device option and VCC
  • STC is typically 0.12%/°C for device options DRV5055A1 - DRV5055A4 and is 0%/°C for DRV5055Z1 - DRV5055Z4 options
  • TA is the ambient temperature
  • VOUT is within the VL range

As an example, consider the DRV5055A3 with VCC = 3.3 V, a temperature of 50°C, and 67 mT applied.
Excluding tolerances, VOUT = 1650 mV + 67 mT × (15 mV/mT × (1 + 0.0012/°C × (50°C – 25°C))) = 2685 mV.
