Part Number: LP5861 Hi sir,
What's the VSYNC PIN function behavior in mode 2?
What's the difference with/without VSYNC command in mode 2 ?
Customer wants to connect VSYNC PIN to LED_STROBE to control and realize PGS application (Pseudo-Global Shutter…
Part Number: LP5861 Tool/software: Hi
When LP5861is powered on, the MC data is set to default value, which is 15 mA.
LED current is default when powered on and device enable.
I use LED with max current 10mA.
How to set the initial current value…
Part Number: LP5861 Other Parts Discussed in Thread: TLC59116 Tool/software: If I connect VLED to 5V and don't use the internal FET can I connect two or three LEDs in series and connect the anode of the top LED to say 12V? All of the diagrams show the…
Part Number: LP5861 Tool/software: I have received samples of the LP5861 and have connected it up. I tied Vsync low through a resistor and programmed it to MODE1.
I have IPS tied low and A1 = 3.3V and A0 = 0V. It responds to 0x48 - 0x4A when I talk…
Part Number: LP5861 Other Parts Discussed in Thread: USB2ANY Hello,
we're developing a LED driver application with the LP5861 in mode 1. We have only an I2C interface available to the driver and no means to control VSYNC from a host MCU. The LED driver…
Part Number: LP5861 Tool/software: I'm planning on just tying the VIO_EN pin high, but was wondering why the datasheet doesn't specify the VIO_EN current when active. I'm guessing that my uController could supply enough current using a typical GPIO since…
Part Number: LP5861 Tool/software: Hi, I'm designing a circuit which can be summarized as LP5861 driving 16 LED brightness via analog dimming. Each LED connected to each channel of L5861. Only 8 LED is turned on at the same time, it's either channel 0…
Part Number: LP5861 Tool/software: I'd like to use the LP5861 (or similar chip) in a noise sensitive application. Is it possible to configure the LP5861 chip PWM settings so that the there is no switching on the outputs and use just the analog dimming…
Part Number: LP5861 Hi -
For LP5861 18-Channel LED Driver, it has MC settings, CC (Group Current) setting, and DC (Dot Current).
Can LP5861 handle dynamic modification to DC (Dot current settings) for individual LED ? Are there any drawback to changing…
Part Number: LP5861 Hi expert,
1. How do you calculate the fault reporting time of LOD and LSD? What does 4 sub-periods time meant?
2. Also in 8.3.6, it states that the removal function can be set by enabling "LOB_removal" bit in Dev_config2…
