Part Number: LP5009 Tool/software: Our four LED board (photo, below) is configured as follows:
LED 1 (UV): OUT_0
LED 2 (UV): OUT_1
LED 3 (UV): OUT_2
LED 4 (White): OUT_3
Each LED shall display independently in sequence.
These initialization commands…
Part Number: LP5009 Hi TI support team
We measure SDA Rise time & SCL Rise time. it cannot meet the SPEC.
I think this LP5009 SPEC is defined by 400KHZ. Our I2C is 100K so it will fail.
Do you have Rise time SPEC for 100KHZ?
Part Number: LP5009 We have mulitiple RGB strings with seven LEDs in series. the applied voltage is 24V. To drive strings in parallel we use current mirrors, as shown below.
Whats the maximum voltage on any of the current sink input pins?
I mean, when…
Part Number: LP5009 Hello,
I use LP5009 to generate the PWM signal for the LED driver.
I intend to discretize the PWM signal into 4096 steps,
The PWM resolution of the LP5009 is 12 bits, which means 4096, so I think it should be able to achieve 4096 discrete…
Part Number: LP5009 Other Parts Discussed in Thread: LP5012 , LP5562 Hi TI supporter team,
Currently, I tried the commands as below but the LED are not be turned on.
i2cset -f -y 1 0x14 0x00 0x40 i2cset -f -y 1 0x14 0x02 0x0f i2cset -f -y 1 0x14 0x03 0x…
Part Number: LP5009 Other Parts Discussed in Thread: LM5009 , LP5569 Hi,
LP5569 has a feature to limit the current for each channel individually. Is this also possible with LM5009?
For example with LM5009, if I use an RIREF to set the global current limitation…
Part Number: LP5009 I noticed the default stage of output is 00h.The color mixing percentage is 0%.
But for 00h, I want to check whether the output pin stays at HIZ stage for the perspective of Hardware.
Because the customer would not like the open drain…
Part Number: LP5009 Hello,
I would like to ask, what could happen for LP5009, if the 3.3V supply is missing, LEDs are connected with the OUT_xy pins and they are supplied by 5V? (RGB-Drive is inactive). Could it be damaged?
Thank you and best regards…
