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.
