MC33689DPEW

MC33689DPEW is a system basis chip with LIN transceiver. It 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. It has a 5.0V, 50mA 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. One 50mA and two 150mA high side switches with output protection are available to drive inductive or resistive loads. The 150mA switches can be pulse-width modulated (PWM). Two high voltage inputs are available for contact monitoring or as external wake-up inputs.
