Supply
The supply (CH1 pin 9) is used to power the device. The supply is internally protected against reverse polarity and low-energy voltage spikes.
Refer to the Electrical Specification for more details on the device supply.
Warning
The supply line must be protected against high-energy voltage events exceeding device limits
GND
All GND (ground) pins are connected internally.
5 V Supply Output
The +5 V output can be used to power external devices. The power can be toggled via the device configuration. The output can deliver 1.5 A @ 5 V continuously.
Danger
Connecting external input power to this pin can permanently damage the device
Warning
External protection (such as clamp diodes) must be installed if inductive loads are connected to the 5V Supply Output
CAN L/H
Warning
CAN-bus requires no common reference (ground). However, it is recommended that GND (ground) is carried along with CAN-L/H to prevent that the common-mode voltage is exceeded (resulting in transceiver damage)
LIN VBAT
The LIN-bus positive reference. Supports systems operating from 4V to 24V.
LIN1 VBAT: Pin is shared with device supply and shares the supply input protection circuit
LIN2 VBAT: Tolerates voltage spikes up to 48V. Spikes above this can damage the interface
LIN Data
LIN-bus single-wire data line referenced to LIN VBAT.
Wiring example
Below example illustrates how the CANedge CAN-bus 1 (channel 1) can be connected.
