MC33889 Datasheet | Motorola Semiconductor

features : - Vdd1: 5V Low drop voltage regulator, current limitation, over temperature detection, monitoring and reset function. 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 modes. - Low stand-by current consumption in stop and sleep modes - Built in Low speed 125KBaud fault tolerant CAN physical interface, patible with Motorola MC33388. - External high voltage wake-up input, 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 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.
