ZHCSH94F October 2017 – May 2022 TLIN1029-Q1
If the EN pin is high at power up the device will power up in normal mode. If the EN pin is low, it will power up in standby mode. The EN pin controls the mode of the device. In normal operational mode the receiver and transmitter are active and the LIN transmission up to the LIN specified maximum of 20 kbps is supported. The receiver detects the data stream on the LIN bus and outputs it on RXD for the LIN controller. A recessive signal on the LIN bus is a logic high and a dominant signal on the LIN bus is a logic low. The driver transmits input data from TXD to the LIN bus. Normal mode is entered as EN transitions high while the TLIN1029-Q1 is in sleep or standby mode for > tMODE_CHANGE plus tNOMINT.
