Note:
15. Start-Up Time (tstart) refers to the internal start-up time from when SD is released to when the device
is ready to activate the PWM outputs. The total power-up time from SD release to the PWM outputs
becoming active will vary based on the input signal, not exceeding the Start-Up Time + Zero Crossing
Power-Up Timeout (tstart + ttimeout). For more information refer to Section 5.4.
