Data Sheet
Function
Reset Input/Output; open drain output, integrated pull-up resistor; active low.
SPI Chip Select Not Input; CSN is an active low input; serial communication is
enabled by pulling the CSN terminal low; CSN input should be set to low only when
CLK is low; CSN has an internal pull-up resistor and requires CMOS logic level
inputs.
SPI Clock Input; clock input for shift register; CLK has an internal pull-down resistor
and requires CMOS logic level inputs.
SPI Data Input; receives serial data from the control device; serial data transmitted
to SDI is a 16-bit control word with the Least Significant Bit (LSB) transferred first:
the input has a pull-down resistor and requires CMOS logic level inputs; SDI will
accept data on the falling edge of the CLK signal.
SPI Data Output; this tri-state output transfers diagnostic data to the control device;
the output will remain tri-stated unless the device is selected by a low on Chip Select
Not (CSN).
Ground
Not connected
Power Supply Input; block to GND directly at the IC with ceramic capacitor. Ensure
to have no current flow from PIN8 to PIN9. PIN8 and PIN9 can be directly connected.

LIN Bus 1; Bus line for the LIN interface, according to ISO. 9141 and LIN
specification 2.1 as well as SAE J2602-2.
PNP Shunt; External PNP emitter voltage.
PNP Base; External PNP base voltage.
Ground
External PNP Output Voltage
Interrupt Output, configuration Input; used as wake-up flag from SBC Stop Mode
and indicating failures. Active low. Integrated pull up. During start-up used to set the
SBC configuration. External Pull-up sets config 1/3, no external Pull-up sets config
2/4.
Voltage Regulator Output; 5 V supply; to stabilize block to GND with an external
capacitor.
Voltage Regulator Output; 5 V supply; to stabilize block to GND with an external
capacitor.
Supply Input; for the internal HS CAN cell.
CAN High Line; High in dominant state.
Termination Output; to support recessive voltage level of the bus lines.
CAN Low Line; Low in dominant state.
Ground
CAN Transmit Data Input; integrated pull-up resistor.
CAN Receive Data Output
LIN Transceiver Data input; according to ISO 9141 and LIN specification 2.1 as
well as SAE J2602-2. integrated pull-up resistor.
