3.7. Magnetic Characteristics at T_J = –40 °C to +170 °C, V_DD = 4.5 V to 24 V
Typical Characteristics for V_DD = 12 V
Magnetic flux density values of switching points (Condition: –10 mT < B₀ < 10 mT)
Positive flux density values refer to the magnetic south pole at the branded side ot the package. ΔB = B_S1 – B_S2
