Electrical and Magnetic Parameters
Calculation of the ambient temperature:
e.g. for V_S = 12.0 V, I_Styp = 5.5 mA, V_QSATtyp = 0.3 V and 2 x I_Q = 10 mA :
Power Dissipation: P_DIS = 72.0 mW.
In T_A = T_j – (R_thJA × P_DIS) = 175°C – (190 K/W × 0.072 W)
Resulting max. ambient temperature: T_A = 161.3°C
