  • TPS63810: I2C undershoot on TPS63810

    Part Number: TPS63810 Hi Team, Currently customer uses TPS63810 in their smartphone project and they found there is undershoot in I2C SDA from High to low. The waveform is following: External Pull-up voltage is 1.8V and the SOC is STM32 with pull…

  • TPS63810: I2C and EN voltage levels

    TI Thinks Resolved
    Part Number: TPS63810 Tool/software: Good morning, I'm trying to understand if I can directly control I2C and EN with MCU I/Os operating at 0-1.8V. Looking at the datasheet, all examples are at 3.3V. However, checking section "7.5 Electrical Characteristics…
