Frequently Asked Questions
How can I adjust the lead angle setting?
Use input pins LA0 and LA1: Low, Low for 0 degrees; High, Low for 7.5 degrees; Low, High for 15 degrees; and High, High for 30 degrees.
What is required to disable PWM duty-100% signals?
A signal of High for 250 ns or longer is required to bypass the duty-100% input.
Are there any limitations regarding product use in critical applications?
The products are intended for general electronics applications and are not warranted for usage in equipment requiring extraordinarily high quality or reliability (e.g., medical instruments, aircraft systems).
What does SEL_OUT control?
SEL_OUT selects the synthesis method of the burn-in signal and PWM signal; Low enables Upper PWM, and High enables Upper/Lower alternate PWM.
