freescale公司的MC33903/4/5是第二代的系统底子芯片(SBC),能作为MCU的先进电源管理,并集成了几种先进的集成电路如传感器和CAN收发器,内置了增强高速CAN接口(ISO11898-2和-5),以及当地和总线故障诊断,掩护与故障安全利用模式.主要用在航空和水下系统,汽车和呆板人系统,农场设备,灯和电感负载控制,DC马达控制,工业鼓励控制等.本京电港论坛文章先容了MC33903/4/5系列产物主要特点,框架图和简化应用框图,评估板KIT33905D5EKEVBE主要特性,创建框图,电路原理图纸,质料清单和PCB线路板元件结构图和走线图.

The 33903/4/5 is the second generation family of the System Basis Chip (SBC). It combines several features and enhances present module designs. The device works as an advanced power management unit for the MCU with additional integrated circuits such as sensors and CAN transceivers. It has a built-in enhanced high-speed CAN interface (ISO11898-2 and -5) with local and bus failure diagnostics, protection, and fail-safe operation modes. The SBC may include zero, one or two LIN 2.1 interfaces with LIN output pin switches. It includes up to four wake-up input pins that can also be configured as output drivers for flexibility. This device is powered by SMARTMOS technology.

This device implements multiple Low-power (LP) modes, with very low-current consumption. In addition, the device is part of a family concept where pin compatibility adds versatility to module design.

The 33903/4/5 also implements an innovative and advanced fail-safe state machine and concept solution.

MC33903/4/5系列产品主要特性:

•Voltage regulator for MCU, 5.0 or 3.3 V, part number selectable, with possibility of usage external PNP to extend current capability and share power dissipation
•Voltage, current, and temperature protection
•Extremely low quiescent current in LP modes
•Fully-protected embedded 5.0 V regulator for the CAN driver
•Multiple undervoltage detections to address various MCU specifications and system operation modes (i.e. cranking)
•Auxiliary 5.0 or 3.3 V SPI configurable regulator, for additional ICs, with overcurrent detection and undervoltage protection
•MUX output pin for device internal analog signal monitoring and power supply monitoring
•Advanced SPI, MCU, ECU power supply, and critical pins diagnostics and monitoring.
•Multiple wake-up sources in LP modes: CAN or LIN bus, I/O transition, automatic timer, SPI message, and VDD overcurrent detection.
•ISO11898-5 high-speed CAN interface compatibility for baud rates of 40 kb/s to 1.0 Mb/s
•Scalable product family of devices ranging from 0 to 2 LINs which are compatible to J2602-2 and LIN 2.1

•Aircraft and marine systems
•Automotive and robotic systems
•Farm equipment
•Industrial actuator controls
•Lamp and inductive load controls
•DC motor control applications requiring diagnostics
•Applications where high-side switch control is required
