原理图绘制
使用原理图符号布局电路元件，然后进行电气连接。从放大器到真空管各种符号应有尽有，同时还可以创建自定义符号，因此您几乎可以设计任何电路。通过访问 DigiKey 广泛的零件数据库，您还可以浏览并指定任何可订购的零件。
框图构建
使用系统模块在概念层面完善您的想法。更高级的组件可帮助您对想法进行更广泛的规划。这是一个个功能强大的块链库，可以让您快速布局各种电路功能。完成设计后，可保存并与您的同事分享。
流程图创建
流程图创建选项有助于您将概念转化为设计。使用库中的箭头、图形、UML 符号等来梳理流程并为每个阶段作注释。插入文本框、数学函数/公式、图片或链接，帮您说明目标，并使您的计划更易理解。

The KIT33907AEEVB and KIT33908AEEVB evaluation boards demonstrate the functionality of the SMARTMOS MC33907 and MC33908 power system basis chips, respectively. These ICs are equipped with an intelligent power management system including safety features targeting the latest ISO26262 automotive functional safety standard. The evaluation board is a standalone board that can be used either with a compatible microcontroller or with PC. In the latter case, it is necessary to use a KITUSBSPIDGLEVME accessory interface board. The MC33907 and the MC33908 are multi-output ICs with power supply and HSCAN transceiver. These devices have been designed specifically for automotive market. All features of thse two ICs are the same except that the MC33907 is designed to support up 800 mA on VCORE, while MC33908 will support up to 1.5A on VCORE. The DC to DC converter that supports up to 1.5A on VCORE has the following applications: electrical power steering, engine management, battery management, active suspension, gearbox, transmission, electrical vehicle (EV), hybrid electrical vehicle (HEV) and advanced driver assistance systems.

The design is comprised of MC33879APEK configurable octal serial switch with open load detect current disable and incorporates SMARTMOS technology. It is used to control the dc motors that are interfaced to the system. The 5V supply and VBAT are provided with capacitor filters. The dc motors are placed to the different parts of the robot. The platform revolute is installed at the surface so the robotic arm itself can rotate horizontally (azimuth movement). The arm revolute is installed directly above the platform so the robot can rotate vertically (elevation movement). The horizontal and vertical clipper serves as the fingers of the robot that will have direct contact to the target object. The MCU or microcontroller unit is used as a host controller of the system and it also processes the robot data input/output. The design is applicable to robotic development with design considerations. It is applicable to different types of dc motors assuming that the power requirements are met. The design is flexible that only few modifications required so it can be used for other applications.

The circuit has a frequency response of up to 3 MHz with a gain that is about 30 dB. Field-effect transistor Ql is configured in the common-source self-biased mode; optional resistor R1 allows you to set the input impedance to any desired value. Commonly, it will be 50 . The signal is then direct-coupled to Q2, a common-base circuit that isolates the input and output stages and provides the amplifier`s exceptional stability. Last, Q3 functions as an emitter-follower, to provide low output impedance (about 50 ).If you need higher output impedance, include resistor R8. It will affect impedance according to this formula: Rs ~ ^0lJT - 50. Otherwise, connect output capacitor C4 directly to the emitter of Q3. This design is used in telecommunication system with frequency range of 1.8MHz to 2000MHz. Its basic applications include driving to another high power source, driving a transmitting antenna, microwave heating, and exciting resonant cavity structures. Among these applications, driving transmitter antennas is most well known. The transmitter–receivers are used not only for voice and data communication but also for weather sensing in the form of a RADAR.
