System Basis Chip with LIN Transceiver
33689D
The 33689 is a serial peripheral interface (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 provides full SPIreadable diagnostics and a selectable timing watchdog for detecting errant operation.
The LIN transceiver waveshaping circuitry can be disabled for higher data rates.
