L9637D K Line Transceiver LO pin Functionality

[samshubh421]

Hello Concern,

We are considering the L9637D in one of our program as we are checking for LO pin functionality.
As there is very limited details in the datasheet.

Hello,

Please find the answer from our expert below.

L9637D contains a bidirectional K-line. It is receiver when the K pin is driven by K_line and RX pin report translated signal to microcontroller. It is transmitter when the microcontroller drives TX pin and L9637D drives K-line.

 There is even L-line only as receiver. It is the same than K-line receiver. L_line protocol is almost the same than K-line protocol, but it is normally intended as unidirectional bus to program sensors. In L9637D, only receiver is implemented.
