System Basis Chip with LIN Transceiver

The 33689 is a SPI-controlled System Basis Chip (SBC) that combines many frequently used functions in an MCU-based system plus a Local Interconnect Network (LIN) transceiver. Applications include power window, mirror, and seat controls. The 33689 has a 5.0 V, 50 mA low dropout regulator with full protection and reporting features. The device provide full SPI-readable diagnostics and a selectable timing watchdog for detecting errant operation.
