DIGITAL INTERFACE SPECIFICATIONS AND CHARACTERISTICS

POWER-UP & POWER-DOWN CHARACTERISTICS

Note:

15. Start-Up Time (t

start

) 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 (t

start

timeout

). For more information, refer to Section 5.4.
