Notes
44. This parameter is guaranteed by design, not production tested.
45. As duty cycle approaches the limit of 100% or 0% there is a maximum and minimum which is not achievable due to deadtime,
propagation delays, switching times and charge time of the bootstrap capacitor (for the High Side FET). 0% is available by definition
(FET always OFF) and unlimited ON (100%) is possible as long as gate charge maintenance current is within the trickle charge pump
capacity.
46. A Minimum Deadtime of 0.0 can be set via an SPI command. When Deadtime is set via a DEADTIME command, a minimum of 1 clock
cycle duration and a maximum of 255 clock cycles is set using the internal time base clock as a reference. Commands exceeding this
value limits at this value.
47. Blanking time, t BLANK , is applied to all phases simultaneously when switching ON any output FET. This precludes false errors due to
system noise during the switching event.
48. Without considering any offsets such as input offset voltage, internal mismatch and assuming no tolerance error in external resistors.
