Fail-safe Features
• The reverse current is < 2 µA at pin LIN during loss of VBAT; this is optimal behavior for bus
systems where some slave nodes are supplied from battery or ignition.
• Pin EN provides a pull-down resistor to force the transceiver into Sleep Mode if EN is
disconnected.
• Pin RXD is set floating if VBAT is disconnected.
• Pin TXD provides a pull-down resistor to provide a static low if TXD is disconnected.
• The LIN output driver has a current limitation, and if the junction temperature Tj exceeds the
thermal shut-down temperature Toff, the output driver switches off.
• The implemented hysteresis, Thys, enables the LIN output again after the temperature has
been decreased.
