Hello,
Background:
LP8860-Q1 is operated with all outputs (OUT1 - OUT4) shorted together to maximize LED current up to 600 mA. 8 LEDs are operated in series with Vf between 2.75V and 3.5V for each LED.
Questions:
1) What are the EEPROM parameters for this configuration ? LED_STRING_CONF[2:0] -> 110 or 101 ?
2) Will fault detection of Shorts & Open still work ? Is there additional configuration necessary ?
3)The boost adaptation and protection is explained in Figure 29 of datahsheet. With all outputs on same voltage level, will comparator levels work properly ?
4) Is it possible to detect the short / Open of a single LED ?
Best Regards
Martin
