Freescale is launched analog Engine Control Product Series Extended SmartMosTM product lines include signal regulation, H-bridge (H-Bridge) and output driver assemblies for Freescale Auto Microcontrollers.
Texas Austin - June 19, 2007 - Today's car requires advanced engine control solutions to meet customers in performance, fuel efficiency and environmental protection. In order to meet these challenges, the leading semiconductor product supplier Freescale semiconductor in the automotive industry is about to launch six standard SmartMosTM simulation products for engine management applications.
The engine control module is an advanced system that requires diagnostics and dedicated control functions to monitor environmental inputs, control complex loads, while running in a harsh driving environment. With Freescale's simulated products, manage complex engine control tasks can be reliably and efficient.
Freescale is increasingly rich in simulated product applications for large current power systems, including output drivers, signal monitoring and regulatory devices and H-shaped bridges. Such products can be mixed with Freescale MPC55xx 32-bit microcontroller (MCU), providing large flexibility to support multiple multi-cylinder engine control applications. MPC55XX MCU Based on Power ArchitectureTM technology, MPC55XX MCU is a comprehensive synthetic system (SOC) device optimized for automotive applications, including power system control.
CHRIS Webber, vice president of Strategy Analytics Automotive Practice, said: "The complexity of engine control will continue to increase, because people are constantly developing next-generation systems to achieve more stringent car exhaust emission legal restrictions. Sensor, transistors and engine MCUs The mixed signal connection accounts for a large proportion of circuit design complexity and cost. In order to control costs and provide enhanced performance, electronic module engineers are increasingly requires standard IC products to provide greater design flexibility and higher feature integration. "
In the past 25 years, Freescale has been in a leading position in providing simulation, mixed signals and power products to the automotive market. Freescale's SmartMos technology combines high density, high speed logic with precision analog and high voltage, large current power circuitry. With the serial peripheral interface (SPI) communication protocol, SmartMOS devices can be seamlessly synergistic and seamlessly synergist of Freescale industry's leading automotive MCU product lines.
Freescale Vice President and General Manager of General Manager of Hybrid Signals and Dynamics said: "Freescale's high-performance simulation and mixed signal products are intended to provide reliable and efficient solutions to solve the complexity of engine control. We are committed to Using advanced SmartMOS technology to develop highly integrated innovative simulation products to help automotive designers reduce power consumption, save motherboard space and system costs. "
Engine control solutions based on the following Freescale analog devices will be demonstrated on the Freescale Technical Forum (FTF) held in Orlando, Florida from June 25th to 28th.
Output driver MC33800 is a 16 channel multifunction output driver with 8 low-end drives, 6 field effect transistors (FETs) front drives and 2 constant current low-end drivers. With the MCU interface known as "Swiss Army Sword", the MC33800 can control relays, engines, solenoids, lighting, vacuum tubes, and heating tail gas-containing (HEGO) sensors. Although it is best for engine and transmission control, the device is also ideal for many other applications, such as electric power steering, four-wheel drive control, industrial and commercial control systems for diagnostic reports and fault protection.
The MC33810 low-end driver provides engine control MCU and gasoline engine ignition, multi-function programmable interface between fuel injection assemblies. Its applications include cars, motorcycles, industrial engines, generators, offshore ships, and other entertainment and leisure vehicles. MC33810 is one of the first flexible engine control interface circuits that can be easily extended for various engine cylinders. The device integrates 4 low-end drivers and 4 pre-drives that support PWM, which can be configured to drive injectors, solenoids, external FETs or IGBTs. The MC33810 can greatly reduce the number of components in engine control devices, reduce their volume, reduce costs, and complexity.
Signal monitoring and adjustment MC33811 is a 5 channel solenoid monitoring device for ensuring normal operation of the solenoid. The device determines whether the solenoid opening and closing is problematic by monitoring the current waveform of the solenoid. Simple SPI messages can inform the MCU solenoid drive to success or whether it has failed. Its applications include automatic shifting, injectors, and other control vacuum tube transistors.
MC33975 is an enhanced interface IC that detects 24 switch inputs: 14 to the ground switches and 8 booths to ground or batteries. All this 22 input can be configured to be analog signal inputs used by multiplexing and buffering after the chip external circuit. As one of the Freescaleldo exchange detection interface series, MC33975 can be connected to any MCU that supports SPI, providing protected switch-level interfaces and analog input signal functions. The device has enhanced, providing a current 32 mA current and input sensing for the exchanged 5V sensor. MC33975 can also be used for automotive body control modules and industrial and commercial control systems.
The H-shaped bridge MC33899 and MC33926 devices are single-chip H-shaped bridge power supply ICs designed for electronic throttle control and low voltage DC power servo engine control applications. The device can drive a DC engine or a bidirectional solenoid controller such as a throttle control or an exhaust gas rectifier sensor. They also provide a powerful solution for harsh power system environments in a compact, ease of packaging.
The MC33899 has a SPI interface to the system MCU to support advanced diagnostics, programmable current limits, and selectable conversion rates. It also provides higher output current than MC33926. One default restart function allows MC33899 to configure high load currents below the programmed current limit.
MC33926 provides simple input control to implement accurate load management without the need for SPI interface. The rich feature of the device is a subset of the widespread programming function of the MC33899. Compared to MC33899, the package volume of MC33926 is smaller. This highly enhanced compact PQFN package makes MC33926 into a small engine controller ideal solution. Technology area
