The TLIN1431x-Q1 is a local interconnect network (LIN) system basis chip (SBC) that integrates a watchdog, high-side switch, limp home capability and highly configurable WAKE input pin. The device self-determines the control method, pin or serial peripheral interface (SPI), at power up. The watchdog defaults to a window watchdog for both control methods but for flexibility the device can be configured as a window or timeout watchdog with greater than 20 different time windows when SPI control is used.

The LIN transceiver provides a 200 kbps fast mode for end of line programming. A high-side switch with diagnostic capability is provided for on board LED. The highly configurable WAKE pin can be used with the high-side switch for cyclic sensing, thus, reducing the ECU sleep current. The WKRQ/INH pin can be configured for a digital wake output (WKRQ) or a VSUP based inhibit (INH) enable pin for an external supply.
