Texas Instruments TLIN1431x-Q1 Automotive LIN SBCs

Texas Instruments TLIN1431x-Q1 Automotive LIN SBCs are a local interconnect network (LIN) system basis chip (SBC) that incorporates a watchdog, high-side switch, limp home capability, and highly configurable WAKE input pin. The TLIN1431x-Q1 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. For flexibility, the TI TLIN1431x-Q1 can be configured as a window or timeout watchdog with greater than 20 different time windows when SPI control is used. The LIN transceiver offers a 200kbps fast mode for end-of-line programming. A high-side switch with diagnostic capability is included for onboard LED. The highly configurable WAKE pin is able to be used with the high-side switch for cyclic sensing, lowering 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.
