TLIN1431-Q1 Automotive LIN SBC

Texas Instruments' LIN physical layer transceiver features an integrated high-side switch and a watchdog

Image of Texas Instruments' TLIN1431-Q1 Automotive LIN SBCTexas Instruments' TLIN1431x-Q1 is a local interconnect network (LIN) system basis chip (SBC) that integrates a watchdog, high-side switch, limp home capability, and a 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 control methods and flexibility, the device can be configured as a window or time-out watchdog with greater than 20 different time windows when the 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 an onboard LED. The highly configurable WAKE pin can be used with the high-side switch for cyclic sensing to reduce 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.
