Part Number: TCA9800 Hi,
We have used TCA9800 as suggested by TI technical support team for pseudo-open drain configuration.
Kindly review the above design, and also please ensure whether the Side A(FPGA) and Side B(Slave) connections are correct…
Part Number: TCA9800 Hi
Actually, The LIN INTERFACE (TJA1020T/CM,118) we are using has TXD, RXD lines as Open-Drain which can support up to 3.3to 5V.
but FPGA interface has Pseudo-Open drain path i.e.,1.2V, we need this LIN interface to be compatible…
