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 Simplified Block Diagram Programmable SPI Dual Voltage Regulator Vsup monitor Vdd1 Monitor HS1 control Mode control Reset Watchdog wake-up input CSB SCLK MOSI Reset INTB 5V/200mA V2CTRL Vdd1 HS1 Oscillator V2 WDOGB Vsup V2 Interrupt Vbat Q1 L0 L1 MISO RX TX High Speed 1Mbit/s Physical Interface CAN L CAN H Rterm CAN Gnd CAN supply L2 L3 Freescale Semiconductor, Inc.
