Unpowered Mode
If battery voltage is connected to the application circuit (see Figure 4-7), the voltage at the VS
pin increases due to the block capacitor. When V
S is higher than the VS undervoltage threshold,
V
Sth, the IC-mode changes from Unpowered to Pre-normal mode. The VCC output voltage
reaches nominal value after t
VCC. This time depends on the VCC capacitor and the load.
NRES is low for the reset time delay t
Reset; no mode change is possible during this time.

Fail-safe Features
During a short circuit at LIN, the output limits the output current to I
BUS_LIM. Due to the power
dissipation, the chip temperature exceeds t
LINoff and the LIN output is switched off. The chip
cools down and after a hysteresis of t
hys, switches the output on again. During LIN
overtemperature switch-off, the V
CC regulator works independently.
There are now reverse currents < 3 A at pin LIN during loss of V
Batt or GND. This is optimal
behavior for bus systems where some slave nodes are supplied from battery or ignition.
During a short circuit at VCC, the output limits the output current to I
VCCn. Because of
undervoltage, NRES switches to low and sends a reset to the microcontroller. The IC
switches into Pre–normal mode. If the chip temperature exceeds the value t
VCCoff, the VCC
output switches off. The chip cools down and after a hysteresis of t
hys, switches the output on
again. Because of Pre-normal mode, the V
CC voltage will switch on again although EN is
switched off from the microcontroller.The microcontroller can then start with normal
operation.
Pin EN provides a pull-down resistor to force the transceiver into recessive mode if EN is
disconnected.
Pin RXD is set floating if V
Batt is disconnected.
Pin TXD provides a pull-up resistor to force the transceiver into recessive mode if TXD is
disconnected.
