TECHNICAL DATA
PIN CONNECTIONS
The MC33989 is a monolithic integrated circuit combining 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 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 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
150mA 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
