TLIN1431EVM User's Guide
This user guide describes the TLIN1431-Q1 evaluation module (EVM). This EVM helps designers evaluate
the device performance, support fast development, and analyze automotive local interconnect network (LIN)
systems using the TLIN1431-Q1 family of LIN system basis chips (SBCs), which include wake functionality,
integrated high-side switch, and watchdog.

Note that LIMP_MCU and WAKE_MCU are outputs, and are not connected to LIMP and WAKE. Thus, for example. a signal cannot be applied to WAKE_MCU that would impact the high-voltage WAKE signal on the TLIN1431-Q1.
