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.
