It has compact component that integrates with the functionality of a microcontroller and a very efficient digital signal controller. It has flexible set of peripherals with low cost solution suited for different applications. The storage part is able to withstand over 2A charge current with 6-bit charge current resolution. The voltage has charge accuracy of +/- 0.6% and 11-bit charge voltage resolution.
Wireless charging has now become the trend in this ever-changing mobile device technology. Wired charging has been slowly overshadowed by this brand new technology. Since today's electronics device consumers wanted a more convenient way of charging, getting rid of messy wires and lost charger problems, the consumers resort to this new type of technology. In response to this demand, engineers and developers have to come up with a design that is power efficient, electrically safe, and convenient.
The wireless charging innovation is getting attention most nowadays. They provide easy access towards technological advancement. Wireless chargers have a concept of inductive charging or commonly known as wireless charging. It is the transmission of an electrical current from a power source to a receiving device without the use of a physical connection. The electrical current is then used to charge or recharge the battery of the receiving device. In this circumstance, the receiving device can be anything from a smartphone or any wearable devices, to a large industrial forklift.
The Local Interconnect Network (LIN) bus is a single wire sub-bus system that is used in vehicles as a communication link for the components within the vehicle automotive system. The LIN bus was created to provide a low cost communication link in automotive networks. Though the Controller Area Network (CAN) bus can provide the features available in LIN bus, the costs of implementing its hardware and software is excessively high for smaller applications such as door locks, sensors, vehicle seats, and so on. That is why car manufacturers created the LIN standard. The LIN consists of a master and multiple slave microcontrollers. It uses a transceiver to interface the digital part of the microcontroller and the physical line.
Local interconnect network or commonly known as LIN is a serial correspondence protocol intended to bolster automotive networks in conjunction with Controller Area Network (CAN). As the least level of a hierarchical system, LIN enables cost-effective communication with sensors and actuators when all the highlights of CAN are not needed.
The automotive industries are now into electronics applications in which embedded systems are already part of its major components. In this design, it features the Peripheral Sensor Interface 5 (PSI5), which is the most efficient standard interface of sensors and electronic control units in automotive. It supports complete airbag system that includes system power mode control, supplies for squib firing, satellite sensors, and local Electronic Control Unit (ECU) sensors and ECU logic circuits. It has dedicated safing state machine that complements the airbag's MCU hardware/software safing approach. The system itself is capable of diagnostics and self-protection.
There are some differences that we need to consider when using CAN instead of using LIN. These two protocols should be used together in which this CAN have its own functionality and purpose in automotive in-vehicle networking. In this design, it uses high-speed CAN transceiver that features cost efficient robustness like high system level ESD performance and very high electromagnetic immunity with low electromagnetic emission without common mode choke or other external components. It is also pin and function compatible with market standard especially in automotive.
This project is fit for use in automotive and industrial network applications. As a Controller Area Network (CAN) transceiver, this device provides differential transmit capability to the bus and differential receive capability to a CAN controller at signaling rates up to 1Mbps. The device is designed for operation in especially harsh environments and includes many device protection features such as under voltage lockout, over-temperature thermal shutdown, wide common-mode range, and loss of ground protection.
The design of the circuit is a DC to DC converter. It supports up to 1.5A on VCORE. It features a DC/DC converter that provides power to MCUs. It also deals with the optimization of energy consumption by using DC/DC linear regulators and ultra-low-power saving modes. The model contains a Serial Peripheral Interface (SPI), an advanced functional safety measure that allows control and diagnostics with the MCUs.
The system is designed to provide power to a 3-phase BLDC motor using Freescale's MCZ33903CD5EK, which provides power management. The Brushless DC (BLDC) motor is a rotating electric machine with a classic 3-phase stator similar to an induction motor. It is equivalent to an inverted DC brushed motor, where the magnet rotates while the conductors remain stationary.
