  • LP5012: Led driver with STM32

    TI Thinks Resolved
    Part Number: LP5012 Hi! In my company project we try to use the LP5012 TI Led driver with STM32 microcontroller. Maybe do you have any prepared library for LP5012 IC ? It would be great.

  • LP5012: No output - check I²C commands / troubleshooting steps?

    TI Thinks Resolved
    Part Number: LP5012 I have two LP5012 integrated onto a pHAT (expansion board) for a Raspberry Pi Zero. After failing to get the device tree driver working, I started to implement a driver in Python with the datasheet as reference. I have confirmed…

  • LP5012: State of output pins before MCU can configure the output?

    Resolved
    Part Number: LP5012 Team, -I assume that the open-drain/open-collector outputs (of OUTx pins) are not driven (ie output stage stays tri-stated) as long as the MCU has done the INITIALIZATION (see fig. 15 of SLVSEH2A). Correct? Is it only in the NORMAL…
