Note: The thermal resistances listed in Table 20 “Package Parameters” on Page 55 must be used to calculate

the corresponding ambient temperature.

Calculation of the Junction Temperature

The total power dissipation PTOT of the chip increases its temperature above the ambient temperature.

The power multiplied by the total thermal resistance RthJA (Junction to Ambient) leads to the final junction

temperature. RthJA is the sum of the addition of the values of the two components Junction to Case and Case to

Ambient.

Example (assuming no load on Vout):

(2)

For moulded sensors, the calculation with RthJC is more adequate.

2) Max. current to GND over Open Drain Output

3) Values refer to an homogenous magnetic field (BXY) without vertical magnetic induction (BZ = 0mT).
