can be calculated by following equation: TOTP, on, min − TA−V R S ⋅ Is T I thJA OTP, on, min − T A DRV = V = − IS S VS ⋅ RthJA The equation considers the power dissipation caused by the current consumption of the IC itself. If the driver current exceeds the calculated threshold the lower spec limit of the overtemperature protection will be exceeded and OTP might be triggered. TOTP, on, min The lower spec limit of the overtemperature protection threshold should not be exceeded to avoid triggering the OTP.
