BD6088GUL
● OUT PWM Control
? PWM A fixed signal is output from OUT1 ~ 4 terminal.
? Allows a slope time to be set in the register via PWM.
32 levels of duties prepared as MAX Duty are sequentially stepped at OUTSLP time intervals.
Bit name: OUTSLP(1:0)
? A PWM cycle can choose 2 value.
Bit name: FPWM
? Forced OFF is made with an OUTCNT terminal.
Bit name: OUT*MD
