Part Number: LP5523
Can you confirm that we can use two LP5523 with the TRIG pins configured as shown in page 50 of the datasheet in Figure 26 as the Typical Application Schematic with both devices running from their internal oscillators? (no external…
Part Number: LP5523 Good morning,
I would like to use the Led driver PN LP5523 that is able to manage up to 9 Leds.
Since I need to drive more than 25mA on each channel, I would like to use 3 channels is parallel connecting 3 output together in order…
Part Number: LP55231 Other Parts Discussed in Thread: LP5523 Hi,
Is it possible to disable charge pump and omit capacitors connected to C1+ C1-, C2+ C2- and VOUT and connect VOUT to VDD (5 V) for LP5523(1)? I don't need charge pump as there is 5 V voltage…
Part Number: LP5523 Hi Team,
My customer request LP5523 to run a pattern immediately when power on, but I2C can not work that fast.
Is it possible to run a pattern without I2C communication?
I think it is not possible. Because LP5523 default is…
Part Number: LP5523 Hi All,
I hope your week is going well. I'm working with a system with several LP5523 chips tied to the same external clock for synchronization.
In section 6.10 of the datasheet, the specification shows a min/max high/low time…
You can set the jumpers to select Vbatt and Vddio from external source, supply both vbatt and vddio with external power supply via current meter. Setup the test condition according to datasheet page 4. Check the reading on the current meter and verify…
Other Parts Discussed in Thread: LP5523 , LP5521 HI,
I tried to research and find a way to control my RGB LEDs to run sequence, then I found LP5523. I could control a simple blink led with LP5523 but how to communicate with another LP5523. I mean, when…
Other Parts Discussed in Thread: LP5523 Dear Sir,
what's the different between internal clock and external clock of LP5523?
what's the pros and cons of internal clock and external clock?
Thanks.
Other Parts Discussed in Thread: LP5523 Problem:
PWM values are not being consistently set when writing to these registers using I2C multiple byte write.
Test Setup:
After I enable the chip I run my driver_init() method that does the following:…
Other Parts Discussed in Thread: LP55231 , LP5523 Hi,
I am trying to find out the differences between the LP5523 and LP55231. Are they essentially the same device in different packages? All I see different right now is basically 1 GPIO pin.
What criteria…
