LIN 2.1/SAE J2602 transceiver

The output driver at pin LIN is protected against overtemperature conditions. If the

junction temperature exceeds the shutdown junction temperature Tj(sd), the thermal

protection circuit disables the output driver. The driver is enabled again when the junction

temperature has dropped below Tj(sd) and a recessive level is present at pin TXD.

If VBAT drops below Vth(VBATL)L, a protection circuit disables the output driver. The driver is

enabled again when VBAT > Vth(VBATL)H and a recessive level is present at pin TXD.
