â3.7.4 About LED SHORT detection
LED SHORT detection donât work by individual ch. The followings are needed for detection.
ã»Detection channel is PWM=H and LED terminal voltage is over LED SHORT detection threshold voltage.
ã»Except for detection ch, any 1ch is PWM=H and LED terminal voltage is under 3V.
ã»The above-mentioned 2 states continue over 4clk of DCDC oscillation frequency.
Detection sequence is the followings.(omit 4clk mask)
