LIN system basis chip integrates a LIN 2.0, LIN 2.1, and SAE J2602-2 compatible transceiver with SPI control for MCU-based automotive body systems. The device includes a 5.0 V low-drop regulator, full SPI-readable diagnostics, a configurable window watchdog, and reset circuitry. Output drivers include one protected high-side switch and two protected low-side switches that can be pulse-width modulated. It operates from a 5.5 V to 18 V nominal supply range, remains functional to 27 V, and supports -40 °C to 125 °C ambient operation for the 33911 version.
