LP5562: LED sink condition when not enabled

David Mckinney

Part Number: LP5562

Are the 4 LED driver current sinks (W,R,G,B) for LP5562 High-Z when EN = 0?

Hi David,

Yes the are High-Z when EN=0 or VDD pull down

Thanks for confirming. Do you know if the outputs can be disabled (high-z) via I2C commands while EN=1? Or only possible when EN=0?

Hi David,

Yes the output pins are high-Z when setting PWM and current registers to 0 at operation.
