This parameter is guaranteed by design, not production tested.
Maximum duty cycle is actually 100% because there is an internal charge pump to maintain the gate voltage in the 100% on condition.
However, in high duty cycle cases, there may not be sufficient time to recharge the bootstrap capacitors during the off time. Large
bootstrap capacitors will allow high duty cycles to be obtained for a short time. For applications needing closer to 100% duty cycle,
external diodes may optionally be used to provide high peak current charging capability to the bootstrap capacitors. These diodes would
be connected between VLS and the Px_BOOTSTRAP pins. In applications with lower gate charge requirements, the maximum duty
cycle can also be increased.
A Minimum Deadtime of 0.0 can be set via a 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.
Without considering any offsets such as input offset voltage, internal mismatch and assuming no tolerance error in external resistors.
