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. Refer to the Electrical Specification for more details on the 5 V output.

Danger

Connecting external input power to this pin can permanently damage the device

Warning

External protection (such as clamping diodes) must be installed if inductive loads are connected to the 5 V 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 4 V to 24 V.

  • 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.
