MC33911BAC

MC33911BAC is a LIN system-based chip with a 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 (LIN) 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 operations. The LIN Protocol Specification 2.0 and 2.1 compliant LIN transceiver has wave shaping circuitry which can be disabled for higher data rates. 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 analogue inputs. The voltage on these pins is divided by a selectable ratio and available via an analogue multiplexer.
