System Basis Chip Lite with Low
Speed Fault Tolerant CAN Interface
The MC33889 is a monolithic integrated circuit combining many functions
frequently used by automotive ECUs. It incorporates a low speed fault tolerant
CAN physical interface.
Main features:
• Vdd1: 5V Low drop voltage regulator, current limitation, over temperature
detection, monitoring and reset function. Total current capability 200mA.
• V2: Tracking function of Vdd1 regulator. Control circuitry for external bipolar
ballast transistor for high flexibility in choice of peripheral voltage and current
supply.
• Four operational modes: normal, stand-by, stop and sleep modes.
• Low stand-by current consumption in stop and sleep modes
• Built in Low speed 125KBaud fault tolerant CAN physical interface,
compatible with Motorola MC33388.
• External high voltage wake-up input, associated with HS1 Vbat switch
• 150mA output current capability for HS1 Vbat switch allowing drive of external
switches pull up resistors or relays
• Vsup monitoring and failure detection
• DC Operating voltage from 5 to 27V
• 40V maximum transient voltage
• Programmable software time out and window watchdog
• Separate outputs for Watchdog time out signal (WDOGB) and Reset (Reset).
• Wake up capabilities: wake up input, programmable cyclic sense, forced
wake up, CAN interface, SPI (CSB pin) and stop mode over current.
• Interface with MCU through 4 Mhz SPI.
• SO28WB package with thermal enhanced lead frame.
