汽车高速CAN总线收发器L9616
Description The L9616 is a bidirectional transceiver for signal conditioning and processing in connection with a CAN controller. Data rates of up to 1 Mbaud are supported using either shielded or non-shielded pair of lines.
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.
