To whom it may concern：
LP8860-Q1 is uesd to support the backlight, which has 4 strings and every string has 11LEDs. (90mA/channel, VLED=34V,typ.)
But ,when the Input Voltage=8.5V, the backlight starts flashing.
the EEPROM setting is:
60 00
61 4F
62 DF
63 D1
64 DF
65 1D
66 70
67 77
68 77
69 71
6A 3B
6B 00
6C 0A
6D 20
6E B0
6F 84
70 C5
71 F3
72 E5
73 E3
74 35
75 06
76 DF
77 FF
78 3E
when the flashing happens, read the register is:
| Read SPI 00 - 00 | |
| Read SPI 01 - 00 | |
| Read SPI 02 - 00 | |
| Read SPI 03 - 4F | |
| Read SPI 04 - 00 | |
| Read SPI 05 - 00 | |
| Read SPI 06 - 00 | |
| Read SPI 07 - 00 | |
| Read SPI 08 - 00 | |
| Read SPI 09 - 00 | |
| Read SPI 0A - 00 | |
| Read SPI 0B - 00 | |
| Read SPI 0C - 00 | |
| Read SPI 0D - 5F | |
| Read SPI 0E - 00 | |
| Read SPI 0F - 08 | |
| Read SPI 10 - 00 | |
| Read SPI 11 - 00 | |
| Read SPI 12 - 10 | |
| Read SPI 13 - 04 | |
| Read SPI 14 - 6D | |
| Read SPI 15 - 04 | |
| Read SPI 16 - 7F | |
| Read SPI 17 - FF | |
| Read SPI 18 - FF | |
| Read SPI 19 - 80 | |
| Read SPI 1A - 00 |
The above results show that BOOST_OCP fault happen，but I do not know how does it happen.
Could someone help to explain it ?
Thank you very much.
