  • TPS929120-Q1: input current and output current

    Resolved
    Part Number: TPS929120-Q1 Question1: When TPS929120-Q1 drives LED, must the input current be larger than output current? For example, Vin=12V. For each channel, Vout=3V, Iout=50mA, 12 channel working. So the input current is large than 50mA*12=0.6A…

  • RE: TPS929120-Q1: How to detect FAULT with MCU

    Resolved
    Hi Elec, I don't think there is a way for TPS929120-Q1 to distinguish communication break or MCU not sending. TPS929120-Q1 will enter fail safe state after the WDTimer overflows. This time can be configured in CONF_MISC4.CONF_WDTIMER. When this is…
