Minimum charge bootstrap time
This value indicates the minimum time each PWM low-side and high-side transistors will be active before transitioning to Operation Enable state. The low-side is activated sequentially (Phase AH → Phase BH → Phase CH) to charge each bootstrap separately. After that, each high-side transistor is also activated sequentially (Phase AH → Phase BH → Phase CH) to charge parasitic capacitances.
The real charge time is application dependent, as this value is the minimum time that the drive will wait to charge a bootstrap.
