Description
INH
1
inhibit output for switching an external voltage regulator if a
wake-up signal occurs
TXD
2
transmit data input for activating the driver to the bus lines
RXD
3
receive data output for reading out the data from the bus lines
ERR
4
error, wake-up and power-on indication output; active LOW in
normal operating mode when a bus failure is detected; active LOW
in standby and sleep mode when a wake-up is detected; active
LOW in power-on standby when a VBAT power-on event is detected
STB
5
standby digital control signal input; together with the input signal
on pin EN this input determines the state of the transceiver;
EN
6
enable digital control signal input; together with the input signal on
pin STB this input determines the state of the transceiver;
WAKE
7
local wake-up signal input (active LOW); both falling and rising
edges are detected
RTH
8
termination resistor connection; in case of a CANH bus wire error
the line is terminated with a predened impedance
RTL
9
termination resistor connection; in case of a CANL bus wire error
the line is terminated with a predened impedance
VCC
10
supply voltage
CANH
11
HIGH-level CAN bus line
CANL
12
LOW-level CAN bus line
GND
13
ground
BAT
14
battery supply voltage
