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 Tool/software: Hello guys,
One of my customers considering using LP5861 for their new products.
At this moment, they have the following questions. Could you please give me your reply?
Q1. Is it no problem to leave VSYNC open when VSYNC…
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 team,
My customer faced a problem during using our LP5861. They found that they cannot control the CS pins.
The schematic is attached, and first you can help review the schematic, whether it has any problems.
LP5861 Schematic.p…
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 register…
Part Number: LP5861 Hello everyone,
I have a confusion on how LP5861 drives LEDs through its high-side PMOS output. From datasheets, Other LP586x ICs except LP5861 are using Time-Multiplexing Matrix Scheme when driving LEDs through their high-side PMOS…
Part Number: LP5861 Other Parts Discussed in Thread: LP5860EVM Hello,
My customer is looking at the LP5861 device and has some questions around power consumption at low output currents. Their concern:
One concern might be the current drain, the first…
Part Number: LP5861 In the I2C Data Format section, the data sheet says "The device supports both independent mode and broadcast mode.". The address table below shows the broadcast address having the five most significant bits set to 10101. There is no…
Part Number: LP5861 Hi Team
For application paralleling 2 channels to get a 100mA output current, how do I setup PWM duty?
I assume since I would need to make both 2 channels sink the same current, the PWM setting for both channels should be the same…
