Functional description L9616

4 Functional description

The L9616 is used as an interface between a CAN controller and the physical bus. The
device provides transmitting capability to the CAN controller.
The transmitter outputs C_H and C_L are protected against short circuits and electrical
transients which may occur in an automotive environment.
In case of short circuit (C_H to C_L, C_H to B) the protection circuit recognizes this fault
condition and the transmitter output stages are disabled with a delay of max. 10 ms to
prevent destruction of the IC and high consumption of supply current IS. If VC_L > VC_L max
the transmitter output stages would be disabled immediately.
Pin ASC makes it possible to select two different modes of operation: high speed
(≤ 1 Mbaud) and low speed (≤ 250 kbaud).
The ASC pin is tied to GND for normal operation at ≤ 1 Mbaud. For slower speed operation
at ≤ 250 kbaud the rise and fall slope of the bus output can be decreased to reduce EMI by
connecting the ASC pin to VS.
