... HIP6603B or HIP6604B MOSFET driver interfaces with the HIP6301. For more information, see the HIP6601B or HIP6602B data sheets. The HIP6301 is capable of controlling PWM power channels. Connecting unused PWM outputs to V automatically sets the number of channels. The phase relationship between the channels is 360 PWM channels ...

... PWM outputs into a three state mode. This condition results in the gate driver removing drive to the output stages. The HIP6301 goes into a wait delay timing cycle that is equal to the Soft- Start ramp time. PGOOD also goes “low” during this time due to VSEN going below its threshold voltage ...
