MC33911BACR2 is a LIN system basis chip with DC motor pre-driver. It is a SMARTMOS Serial Peripheral Interface (SPI) controlled System Basis Chip (SBC), combining many frequently used functions in an MCU based system, plus a Local Interconnect Network transceiver. It has a 5.0V, 50mA/60mA low dropout regulator with full protection and reporting features. The device provides full SPI readable diagnostics and a selectable timing watchdog for detecting errant operation. The LIN Protocol Specification 2.0 and 2.1 compliant LIN transceiver has wave shaping circuitry which can be disabled for higher data rates. It can be pulse-width modulated (PWM). Two high-voltage inputs are available for use in contact monitoring, or as external wake-up inputs. These inputs can be used as high-voltage Analog Inputs. The voltage on these pins is divided by a selectable ratio and available via an analog multiplexer. Applications includes window lift, mirror switch, door lock, sunroof, light control.
