  • PCA9536: The thermal information and power dissipation

    TI Thinks Resolved
    Part Number: PCA9536 Hi Team, Please help to confirm the thermal information of PCA9536DGKR. Data sheet doesn't show Θjc. Also, how to calculate its power dissipation? Please kindly provide the formula. Thanks

  • RE: Detection of connected sensor - DeviceID

    Hi Dejan, From what I have gathered so far, you are attempting to interface with 15 different sensors with 15 different unique I2C addresses? In such case, why do we need an external device such as the PCA9536 to make this work? Since each device has…
