Advance Information
System Basis Chip with High Speed CAN Transceiver
The MC33989 is a monolithic integrated circuit bining many functions frequently used by automotive ECUs. It incorporates:
- Two voltage regulators.
- Four high voltage inputs.
- 1Mbaud CAN physical interface.
- Vdd1: Low drop voltage regulator, current limitation, over temperature detection, monitoring and reset function
- Vdd1: Total current capability 200m A.
- 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 mode)
- Low stand-by current consumption in stop and sleep modes
- High speed 1MBaud CAN physical interface.
- Four external high voltage wake-up inputs, associated with HS1 Vbat switch
- 150m A output current capability for HS1 Vbat switch allowing drive of external switches pull up resistors or relays
- Vsup failure detection
- Nominal DC operating voltage from 5.5 to 27V, extended range down to 4.5V.
- 40V maximum transient voltage
- Programmable software time out and window watchdog
- Safe mode with separate outputs for Watchdog time out and Reset
- Wake up capabilities (four wake up inputs, programmable cyclic sense, forced wake up, CAN interface, SPI and stop mode over current)
- Interface with MCU through SPI
