LP8543: Not giving sensor input for LP8543

Part Number: LP8543
Other Parts Discussed in Thread: TPS61177A, LP8556, TPS61187, TPS61196, TPS61199

Hello

I'm using LP8543 in my project. For this IC I will provide PWM and EN. I'm not going to use any ALS sensor. As per datasheet recommendation in standalone mode I'm not using I2C as well.

ALSI pin I will be connecting it to ground. Then how I need to take care ALSO pin. Can I leave it as unconnected? If no then how I need to take care of that pin.

Please help me out in this concern.

Regards

Hi Nidhi,
For ALSO pin, just leave this pin alone is ok. What's your detail application? We have some other backlight driver:
For 6 channel, you can choose :LP8556, TPS61177A, TPS61187
For 8 channel, you can choose :TPS61196, TPS61199
