Part Number: LP8860-Q1EVM
Hello TI Team:
I got a problem about LED driver LP8860.
after power on, I set register table to be meet my setting. I also attached register table and schematic below.
After setting, I measure LED_Anode vs GND, it has 33V and match my setting in 0x73=22.
But I measure LED_Cathode1/2/3/4 vs GND, they are 0V. Then, I measure LED_Anode vs LED_Cathode 1/2/3/4, the result are 0V.
I'm confused that. I also check SQW output status and I think it should have square-waveform output but it is 0V.
Could you help me to check what it is problem?
Bu the way, after power on and LED driver is enabled, if I don't connect LED light bar to these 4 channels. What status does the driver happen?
