Jared Zhou I have built up and tested 8 prototype circuits, all work fine. Modulation is working with the external FET as expected. There does not appear to be any race condition - External FET and LP5521 can be enabled in either order. Thank you for…
Part Number: LP5521 Hi,
I wondered if LP5521 can be programmed in a way that after POR it will start LED program autonomously without the need of re-programming thru i2c?
Basically, I'd like to see the LEDs go ON right after the power comes ON, without…
Part Number: LP5521 The CLK-32K pin of LP5521 is not connected to the clock. Is it grounded, which will affect the function? For example, respiratory effect function, etc
Part Number: LP5521 Hi
I am using LP5521 in my design with external 32kHz clock to synchronize multiple LED drivers. Could you please let me know what is the capacitive load offered by CLK_32K pin?
I need this info to choose an oscillator of sufficient…
Part Number: LP5521 Other Parts Discussed in Thread: LP5523 Hi Expert,
Customer used LP5523 and LP5521 on their board. They would like to know if we have any Io accuracy data with small current and/or at different Vdd can share? Their Vdd is provided…
Part Number: LP5521 Hi,
Can you please help with the following question regarding enable pin? I am quoting below:
In the data sheet I miss concrete information about the wiring, e.g. at the start of the system, when it must be expected that the control…
Part Number: LP5521 Hello,
I am trying to understand how I can run the LP5521 program mode with the internal clock. The background is I am using LP5521 to control the RGB LEDs, and trying to store some commands into its internal SRAM, and execute the…
Part Number: LP5521 Hi,
I want design a power bank indicator with 3 level (Full > medium > low),
LP5521 is suit able for this kind of design?
And there have LED indicator solution combine the ADC?
Because in currently design, I need a ADC to detect…
