6.3.6 Sensitivity Temperature Compensation for Magnets

Magnets generally produce weaker fields as temperature increases. The DRV5055-Q1 compensates by increasing sensitivity with temperature, as defined by the parameter STC. For device options DRV5055A1 - DRV5055A4, the sensitivity at TA = 150°C is typically 12% higher than at TA = 25°C. For device options DRV5055Z2, the sensitivity at TA = 150°C is typically same as the value at TA = 25°C.
