10.3.1.1 Transmitter Characteristics

The driver is a low-side transistor with internal current limitation and thermal shutdown. There is an internal 30-kΩ pullup resistor with a serial diode structure to VSUP, so no external pullup components are required for LIN responder mode applications. An external pullup resistor of 1 kΩ, plus a series diode to VSUP must be added when the device is used for commander node applications.

Voltage on LIN can go from –40-V to 40-V dc without any currents other than through the pullup resistance. There are no reverse currents from the LIN bus to supply (VSUP), even in the event of a ground shift or loss of supply (VSUP).

The LIN thresholds and ac parameters are LIN Protocol Specification Revision 2.0 compliant.

During a thermal shutdown condition, the driver is disabled.
