  • LP5523: External voltage on LED channel

    Resolved
    Part Number: LP5523 Hi Team, So as part of our design, we are using the LP5523. As one of our requirements we need to have a non-I2C based LED for Fault indication, however we ideally want to double up this LED with the PWM functionality provided by the…

  • LP5523: How do I correspond to 9 channels in the device tree?

    TI Thinks Resolved
    Part Number: LP5523 Hi TI team, I know LP5523 LED driver has 9 channels. Our project uses two LP5523 LED drivers. But we found the LED behave strangely. So I want to confirm if the device tree 'chan0' is corresoinding to 'D1'? Could you…

  • LP5523: Cannot run two blink pattern on two different RGB in parallel

    Part Number: LP5523 Hello, I'm developing a driver for the LP5523 in order to manage 2 RGB LEDs (let's call them B and C) and 1 individual LED (let's call it A). I developed blinking/breathing/etc. patterns using the instruction set. LED A…

  • LP5523: internal clock use with two devices and TRIG for synchronous operation

    TI Thinks Resolved
    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…

  • LP5523: layout guide line for LP5523

    TI Thinks Resolved
    Part Number: LP5523 Hi, Because the layout guide line is too rough and all the pin is very closed, I wanna know if the layout of EVM is able to show or if there are other layout suggestion? EX: width of wire, numbers of layers, device placement..... …

  • LP5523: Concerns/impact on design

    TI Thinks Resolved
    Part Number: LP5523 Hello, I designed in a .47uF, 6.3V rated cap into C1/C2, instead of the recommended .47uF, 10V from the datasheet. I'm not able to find a 10V rated cap in the same package size and I'm not able to have additional design changes.…
