The VD supply undervoltage protection the module when the pre-driver supply voltage falls due to an operating malfunction. It will typically start up at 12 V (typical). The UVP circuit has typically 1 V of hysteresis and will disable the output if the supply voltage falls below 11 V (typical). The driver power supply low voltage protection turns off the gate and will automatically reset when recovering to normal voltage. It does not depend on input signal voltage. 2. The three high-side and three low-side gate driver ICs have their own separate undervoltage protection which functions independently of the other phases. For the low-side drivers, there is one combined fault output; it is therefore not possible to determine which output has caused the desaturation fault. The fault condition is cleared as soon as the input signal is set HIGH (off state, negative logic levels). 3. When using the over-current protection with an external shunt resistor, please set the current protection level to be less than or equal to the peak output current rating (Iop).
