PC33889DW

The PC33889DW is designed as a monolithic integrated circuit combining many functions frequently used by automotive ECUs. It incorporates a low speed fault tolerant CAN physical interface.

PC33889DW has thirteen features. (1)Four operational modes: normal, stand-by, stop and sleep modes. (2)Low stand-by current consumption in stop and sleep modes. (3)Built in low speed 125KBaud fault tolerant CAN physical interface, compatible with motorola MC33388. (4)External high voltage wake-up input, associated with HS1 Vbat switch. (5)150mA output current capability for HS1 Vbat switch allowing drive of external switches pull up resistors or relays. (6)Vsup monitoring and failure detection. (7)DC operating voltage from 5 to 27V. (8)40V maximum transient voltage. (9)Programmable software time out and window watchdog. (10)Separate outputs for Watchdog time out signal (WDOGB) and reset (reset). (11)Wake up capabilities: wake up input, programmable cyclic sense, forced wake up, CAN interface, SPI (CSB pin) and stop mode over current. (12)Interface with MCU through 4Mhz SPI. (13)SO28WB package with thermal enhanced lead frame. Those are all the main features.

Some absolute maximum ratings of PC33889DW have been concluded into several points as follow. (1)Its supply voltage at Vsup would be min -0.3V and max 27V for continuous voltage and would be max 40V for transient voltage (load dump). (2)Its logic inputs would be min -0.3V and max Vdd1+0.3V. (3)Its HS1 voltage would be min -0.2V and max Vsup+0.3V. (4)Its ESD voltage would be min -2kV and max 2kV. (5)Its ESD voltage (machine model) all pins would be min -200V and max 200V. (6)Its junction temperature range would be from -40°C to +150°C. (7)Its storage temperature range would be from -55°C to +165°C. (8)Its ambient temperature (for info only) would be from -40°C to +125°C. (9)Its thermal resistance junction to GND pin would be 20°C/W. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device. And so on.
