Datasheet does not mention anything about the need of Pull-up resistors for LIN_TXD and/or LIN_RXD.
Are these needed?

Hello,

Please refer Figure 32 of the datasheet TLE9262BQXV33XUMA1 (Also attached below)

AnilKumar_1-1646812102477.png

Block diagram in the figure clearly shows a pull up resistor for TXDLIN and Push-pull configuration for RXDLIN.

Hence, external pull ups are not required as they are considered internally.

Moreover, the value of Pull Up resistor for TXDLIN is mentioned in Table 19 Electrical Characteristics (See below)
