MC33689DPEWR2

MC33689DPEWR2 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 transceiver. Applications include power window, mirror, and seat controls. The 33689 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 wave shaping 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. A current sense operational amplifier is available for load current monitoring.
