Hi
I would like to know what kind of function the RGB LED driver "LP5562" can support? such as Breathing light..etc.
Thanks.
Derek.

Hi Monet,
Thanks for your reply.
I am not sure if the LP5562 is the best solution for our application, our product is a wearable device, the RGB LED driver is for RGB LED user indicator, Would you have any other solution you can recommend? it has to be smaller and low power consumption.
Best,
Derek.
Hi Derek,
The package of LP5562 is DSBGA (YQE), 12pins and size of 1.258 x 1.658 mm^2. And it has power save mode which decrease the current to 0.25mA(internal oscillator) or 10uA(external 32kHz clock running) and the engine release the MCU during LEDs lighting.
if you have any other request for application, please contact me.

Hi Monet,
thanks for your reply.
I have another question, can we place the magnetic material to close the LED driver IC?
the link is the magnetic spec, we will use N45.

Hi Monet,
Sorry, I have another question about the Enable pin, I would like to know if there is an internal pull-down in the Enable pin, if not, do you need to add the external pull-down resistor on the Enable pin? thanks.
Derek.
Hi Monet,
Thanks for your reply.
Due to we would like to use the 1.8V from our system to enable the LED driver "LP5562", Can the Enable pin be connected to the 1.8V power rail directly? if so, I am just wondering if we should add the current limit resistor between the 1.8V power rail and the enable pin of LP5562. Thanks.
Derek.
Hi Derek,
The enable pin can be connected to the 1.8V power from the system directly and the current limit resistor is not necessary.
Here is the LP5562 Evaluation board User's guide and you can refer to it.
